GOP struggles to escape Trump trap from Politico
"Republicans condemn their poll leader but don't lift pledge to support his nomination, should he win it. ... Trump's latest gambit, far more outlandish than building a wall along the U.S.-Mexico border or any others, has ratcheted up the pressure on GOP officials to find a way to protect their party brand before it becomes irrevocably tarnished by a man who could be their nominee. They can't snatch away his campaign cash or limit his media exposure; they can't keep him off ballots. The party brass can’t reason with Trump and can't afford to alienate him to the point that he runs as an independent. And they must swallow the reality that many self-identifying Republicans prefer Trump’s nativism and bombast to their more mainstream, inclusive style of conservatism."
