Sen. John Cornyn’s landslide defeat Tuesday immediately raised a pressing question for his GOP colleagues: Will he join the ranks of other Republicans recently vanquished by President Donald Trump and begin bucking the president more?

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.

An average of three polls compiled by 270 To Win predicted Cornyn would lose the nomination by a roughly 8-point margin.
