John Cornyn wants to be seen as a Trump loyalist heading into next year's reelection effort.
Democrats hoping to unseat him want exactly the same thing.

Texas Democrats pounced.
Trump's embrace will both help and hurt the state's senior senator in his bid for reelection, The Dallas Morning News' Todd Gilman says.
