Once again, Donald Trump is taking credit for driving a nail into the coffin of the Senate immigration deal, the technically-still-in-the-works bipartisan effort dreamed up by Mitch McConnell and Chuck Schumer as a way to address the border crisis while approving more funding for Ukraine. “It’s not going to happen,” Trump declared on Saturday at an event in Las Vegas. And once again, Republican voters are quickly coalescing around the notion that only Trump can fix the border crisis—an alarming and pressing issue, with nearly 10,000 migrants crossing from Mexico into the U.S. in a single day last month, a record high—effectively transforming a legislative debate into a political cudgel for Trump to pummel Biden over the next 10 months of this forever election.
