Democrats want Senate Republicans to reverse course and consider the nomination of Merrick Garland to the Supreme Court, but following another round of primary victories for Donald Trump, they’re preparing to call the GOP’s bluff and take the issue to the ballot box.

“We really need to do our job. The American people expect that. I’m looking forward to interviewing this guy and finding out what his credentials are and making sure he’ll uphold the Constitution,” Democratic Senatorial Campaign Committee Chairman Jon Tester, D-Mont., said. “We should have a hearing and we should vote. The fact that they’re going to not follow the Constitution, I believe is going to have implications on this election.”

At a news conference before President Barack Obama nominated Garland, Democratic National Committee Chairwoman Rep. Debbie Wasserman Schultz of Florida; Democratic Congressional Campaign Committee Chairman Rep. Ben Ray Luján of New Mexico; and Sen. Charles E. Schumer of New York were confident they had a better hand to play with Republicans squeezed between their refusal to weigh an Obama court pick and the disruptive nature of Trump’s growing front-running status.

“Some Republican elites will try to tell you Trump is hijacking their party. That is not true. Trump’s campaign and his victory among Republicans was years in the making. Literally years,” Wasserman Schultz said,

alluding to the “hateful vitriol” she said Republicans condoned at town hall meetings during the debate over the Affordable Care Act in 2010. Picking up on Garland’s nomination, Schumer said Republicans wouldn’t gain anything by refusing to even hold a hearing on Garland and detected some change.

“The ice is beginning to crack,” Schumer said, referring to three GOP senators who said they now will at least meet with the federal appeals court judge.
