This New Yorker piece shows just how oblivious institutional Republicans are to the large part they played in nurturing the environment that allows Donald Trump to "suddenly" spring forth. Ryan Lizza:
“It’s very bad,” McCain, who was eager to talk about Trump, told me on Monday when I stopped by his Senate office. The Senator is up for reëlection in 2016, and he pays close attention to how the issue of immigration is playing in his state. He was particularly rankled by Trump’s rally. “This performance with our friend out in Phoenix is very hurtful to me,” McCain said. “Because what he did was, he fired up the crazies.”
McCain, who has long supported comprehensive immigration reform and was a member of the so-called Gang of Eight that successfully pushed immigration legislation through the Senate in 2013, has been at war with the far right in Arizona for years.
“We have a very extreme element within our Republican Party,” McCain said. He then noted that he was personally censured by Arizona Republicans in January of 2014 and has been fighting to push out the extremists in the state G.O.P. ever since. “We did to some degree regain control of the Party.”
“We’ll see how this plays out, but there is some anger in my state,” McCain said. He mentioned the continuing challenges of border security that were vividly highlighted when tens of thousands of Central American minors crossed into America last summer. “People who otherwise might be more centrist are angry about this border situation.”
