“For Republicans running in swing districts this fall, President Donald Trump’s endorsement might hurt more than it helps,” Politico reports.

“In fact, both Democrats and Republicans in the most closely contested races might be wary of being publicly backed by many of the biggest political figures or interest groups this fall, according to new results from The Politico Poll. That’s because getting their backing can, in some cases, generate backlash from voters far greater than any increase in support when compared with other groups.”

“President Donald Trump’s grip on the Republican party will be tested again in Kentucky’s primary today where he’s trying to oust longtime nemesis Rep. Thomas Massie,” Politico reports.

“In what’s been deemed Trump’s monthlong ‘revenge tour,’ the president has successfully sunk the reelection campaigns of members of his own party who have refused his demands, including several Indiana state lawmakers and Louisiana Sen. Bill Cassidy.”

“Massie would be the ultimate trophy in Trump’s payback crusade. The House member has been a growing thorn in Trump’s side for years, opposing the Iran war, aid to Israel and pressing for the release of the Jeffrey Epstein files. Trump endorsed Massie’s opponent and former Navy SEAL Ed Gallrein as both sides poured tens of millions of dollars into what has been billed the most expensive House primary in history.”

“A Massie loss could essentially quash any internal GOP dissension as he moves into the lame-duck phase of his presidency. A win, however, could embolden Massie and other internal critics, further deepening intraparty fractures as Trump’s approval ratings slumps.”

New York Times: “Nancy Pelosi, the first woman to serve as speaker of the House, on Monday threw her significant clout behind a woman in the race to succeed her: Connie Chan, a member of the San Francisco board of supervisors.”

ABC News: “Overturning a new congressional map in Virginia that would have favored Democrats has had an outsized impact on the state’s U.S. House primaries, with at least four high-profile candidates so far suspending their campaigns.”

“With Virginia keeping its current congressional map, which currently has six Democrats and five Republicans, Democratic candidates face the prospect of either running in a GOP-leaning district or of mounting primary bids to incumbent Democrats.”
