Donald Trump - Mainstream Republican?

Click here for Paul Krugman's take on The Donald, an NYT article entitled "The Face of the Base." Update: Here's a quote from Krugtron the Invincible, in an interview on Bloomberg TV:

"So he's a belligerent, loudmouth racist with not an ounce of compassion for less fortunate people," Krugman said, not pulling any punches. "In other words, he's exactly the kind of person the Republican base consists of and identifies with. It's clear that the very things that Upper West Side New Yorkers find detestable about him are exactly what endear him to the Republican base, which is basically people who see in him everything - even the big red face and the yelling - that makes him their kind of guy."
