Massie's loss leaves no doubt about Trump's power over the GOP. 6 takeaways from Tuesday's primaries

NEW YORK (AP) — President Donald Trump scored another win Tuesday against a Republican rival, dislodging Rep. Thomas Massie in Kentucky's primary and knocking out one of his most outspoken critics on Capitol Hill.

Massie has been a particularly difficult thorn in Trump's side. He pushed for the release of the Jeffrey Epstein files, opposed the war with Iran and voted against Trump's signature tax legislation last year. He lost to Trump-backed challenger Ed Gallrein following the most expensive U.S. House primary in history.

While Trump has racked up several wins this primary season, this one perhaps sends an even more forceful message to the president's Republican critics. Massie was entrenched in his deep-red Kentucky district before his feud with Trump exploded, cutting short a congressional career that began in 2012.

Still, Massie will remain in Congress until his term ends in January, and without a Republican primary on the horizon, he now has a freer hand than ever to antagonize Trump.

Massie's defeat is another sign that Republicans give their politicians vanishingly little leeway to cross Trump, who is bent on retribution and has persuaded his voters to defeat his adversaries again and again.

Here are takeaways from primaries in Alabama, Georgia, Idaho, Kentucky, Oregon and Pennsylvania.

Trump's endorsement continues to carry the day

Gallrein was boosted by significant spending from AIPAC and pro-Israel groups, which provided about half of the money benefiting his candidacy, according to AdImpact.

However, there's no question Trump was the key factor. He has repeatedly shown that Republican primary voters will follow his lead, even as his popularity wanes with the broader electorate.

Before Massie's loss, Republican Sen. Bill Cassidy of Louisiana failed to even make a runoff on Saturday, unable to repair his relationship with Trump five years after voting to convict him during his second impeachment trial. And earlier this month, Trump successfully dislodged five of seven Indiana Republicans he targeted for voting against his redistricting plan.

Trump is flexing his influence in other places Tuesday.

In the race for Georgia governor, Trump backed Lt. Gov. Burt Jones in an unexpectedly ugly battle for the Republican nomination. Jones, who comes from a wealthy Georgia family, has given his campaign $19 million. But billionaire Rick Jackson, a healthcare tycoon, has put more than $83 million of his fortune into the race. Trump's endorsement power has rarely been tested against that level of lopsided spending, and Jones and Jackson are heading for a June 16 runoff.

Trump stayed on the sidelines of Georgia's Senate race, leaving a crowded field of hopefuls seeking to take on Democratic Sen. Jon Ossoff, who's running unopposed for his party's nomination. But in Alabama, Trump endorsed Rep. Barry Moore for Senate to replace Tommy Tuberville, who is running for governor.

After staying on the sidelines of a Senate runoff in Texas that's taking place next week, Trump on Tuesday endorsed Attorney General Ken Paxton over incumbent Sen. John Cornyn.

Shapiro succeeds in Pennsylvania primaries

While Trump had a big night on the Republican side, Democratic Pennsylvania Gov. Josh Shapiro showed some political strength of his own.

LIVE RESULTS: Pennsylvania midterm congressional primaries

Shapiro, who may look to succeed Trump in the White House, endorsed four Democrats running for Congress, three of them in contested primaries. And all four won their primaries.

Shapiro's endorsed candidates included Paige Cognetti, mayor of Scranton; Bob Brooks, president of the state firefighters' union; Bob Harvie, a Bucks County commissioner; and Janelle Stelson, a former television news personality who narrowly lost two years ago.

It was a relatively low bar in some cases — Cognetti ran unopposed — but Shapiro did not show any weakness as he plows toward a November reelection in swing-state Pennsylvania that is expected to launch him into the 2028 presidential contest.

Shapiro may have an even stronger case if the four Democrats he picked Tuesday succeed in flipping Republican seats in the fall.

Pennsylvania's Democratic Party chairman Eugene DePasquale told an election night crowd that "no one" is more invested in flipping seats and "taking back the country" than Shapiro.

Trump opponents became politically homeless in Georgia

Georgia offered a case study in just how bad it can get for Republicans who defy Trump — especially those who push back on his false claims of election fraud.

LIVE RESULTS: Georgia midterm congressional primaries

Secretary of State Brad Raffensperger and former Lt. Gov. Geoff Duncan were among the few Republicans to speak out against Trump's attempt to overturn his 2020 loss. They were on the ballot for governor on Tuesday — Raffensperger as a Republican and Duncan as a Democrat.

Both lost decisively.

Raffensperger spent millions of his own money trying to reintroduce himself to Republicans by reminding them of his long career in conservative politics before defying Trump. Duncan, meanwhile, tried to convince Democratic voters that they can trust him after renouncing his prior opposition to abortion rights, gun control and the expansion of Georgia's Medicaid program.

It didn't work.

The president has continued to falsely insist that he only lost the 2020 election because of fraud, and he's spread baseless fears about the upcoming November midterm elections.

But the results for Raffensperger and Duncan may remind Republicans of the risks of pushing back.

The leading Republican candidates in the governor's race, Jackson and Jones, have both questioned or denied the 2020 election outcome. Jackson actually ran a political ad in the weeks leading up to the primary attacking Raffensperger for defying Trump's effort to overturn 2020.

Votes were voided in Alabama

More than 100,000 people cast ballots in four of Alabama's seven congressional districts that may not count.

LIVE RESULTS: Alabama midterm congressional primaries

That's because Republican Gov. Kay Ivey moved just last week to postpone the primaries until Aug. 11, emboldened by the recent U.S. Supreme Court decision that hollowed out the Voting Rights Act. Republicans across Alabama, South Carolina, Louisiana and Tennessee are now scrambling to redraw congressional boundaries to eliminate some majority-Black U.S. House districts to maximize their political advantage.

Over the weekend, thousands of civil rights activists rallied in Alabama against the changes, but the redistricting plan is moving forward. That means ballots cast Tuesday in primaries for Alabama's 1st, 2nd, 6th and 7th congressional districts will be voided, the secretary of state says, while state officials restore a previous set of Republican-drawn district boundaries.

However, the district lines remain the subject of litigation as the NAACP Legal Defense Find and other groups try to stop the use of the new map. If they are successful, the Tuesday primaries will determine the party nominees.

You'd be excused for being confused. Alabama voters still chose nominees Tuesday as planned for the 3rd, 4th and 5th congressional districts, as well as for U.S. Senate and a full slate of state and local offices.

Americans are in no mood for higher gas prices

Oregon voters overwhelmingly rejected a 6-cent gas tax increase proposed by the state's Democratic lawmakers.

LIVE RESULTS: Oregon midterm state and congressional primaries

The measure was failing by huge margins in every county, crossing every political divide — liberal and conservative, urban and rural, prosperous and struggling.

Tax proponents may have fallen victim to bad timing, with the vote coming as Americans already feel stretched by high gas prices brought on by the war in Iran.

Oregon legislative Democrats voted last year for the tax increase and a series of related fee hikes to help pay for road improvements and plug a hole in the state's transportation budget. Republicans responded by launching a successful referendum campaign to put the issue before voters.

The failure of the gas tax was no surprise to Democrats. It also ran counter to the party's national strategy that relies on channeling voter angst about the high cost of living to win back control of Congress.

Rep. David Scott's death is a reminder of Democratic gerontocracy

The late Rep. David Scott, D-Ga., was the fourth Democrat to die in office this term, fueling a growing restlessness on the left over the party's aging leadership. Scott, who was 80 when he died, was seeking a 13th term.

Scott's name appeared on the ballot alongside five other candidates running in the Democratic primary, but votes for him will not be counted.

State Rep. Jasmine Clark won the nomination Tuesday night, and she is almost certain to win the general election in a district that tilts overwhelmingly toward the Democrats.

Young Democrats have been challenging their elders in primaries around the country. Although some have fallen short, the races have channeled angst that an aging generation of lawmakers is unable or unwilling to mount a bare-knuckles opposition to Trump.
