Incumbent GOP Sen. John Cornyn lost to AG Ken Paxton for the Republican Texas primary. Trump endorsed Paxton, but not because Cornyn voted to impeach.

The vast majority of the $109 million in campaign ad spending is tilted toward John Cornyn.

Trump’s decision to back state Attorney General Ken Paxton against GOP Sen. John Cornyn jolted the Republican Senate primary in Texas.

Cornyn led the March primary with 42% of the vote, narrowly ahead of Paxton’s 40.5%, sending both to a runoff.
