President Donald Trump has not endorsed a candidate for the Republican Senate primary in Texas, setting up a significant showdown in the state where the GOP is desperately trying to prevent a potential loss. As of Tuesday evening, Trump had not yet chosen between Sen. John Cornyn and challenger Ken Paxton, the Texas attorney general. The deadline for candidates to drop out of the race also expired. This could trigger a significant swing in the hotly contested race. The president previously stated he would withhold his endorsement until the SAVE America Act, which requires voters to provide voter ID before voting, was on his desk. The winner of the Texas primary runoff will face Democrat James Talarico in the November midterms.
