Senate Majority Leader John Thune is getting eaten alive by his own base after quietly shelving Donald Trump's signature voter fraud legislation — and the knives are out.Rep. Anna Paulina Luna (R-FL) lit the fuse Friday with a single scorched-earth post: "Just so America knows, after two weeks in recess, John Thune is no longer considering the SAVE America Act."The SAVE America Act, Trump's prized legislation requiring proof of citizenship to register to vote, has been a cornerstone of the MAGA election integrity agenda. It follows years of GOP lies pushing widespread voter fraud claims.Thune's decision to drop it after a two-week congressional recess left true believers feeling blindsided and betrayed by the man the party put in charge of the Senate.The announcement triggered an immediate meltdown across MAGA world, with Trump loyalists turning their fury on the Senate's top Republican with a ferocity usually reserved for Democrats."John Thune is pathetic," wrote one user. "Traitor to the republic," fumed another, adding a call for "tar and feathers."Georgia state Sen. Greg Dolezal, a self-described Trump conservative running for lieutenant governor, called it "the largest blown political trifecta in history" and demanded Thune be replaced. "Absurd. Replace Thune. This is the largest blown political trifecta in history. Y’all have a mandate-get it done," he wrote on X.Others called for his resignation outright."The American people are being betrayed," wrote one account. "This will not stand," echoed another.Some are already calling for primary challengers. Others are demanding Sens. Mike Lee (R-UT) and Ted Cruz (R-TX) force Thune out.Jeannette Garcia of Turning Point USA added, "Unacceptable. Pass The Save Act NOW!"
