NY Times columnist Paul Krugman has some choice comments about the 10 GOPlins on that stage.
For while it’s true that Mr. Trump is, fundamentally, an absurd figure, so are his rivals. If you pay attention to what any one of them is actually saying, as opposed to how he says it, you discover incoherence and extremism every bit as bad as anything Mr. Trump has to offer. And that’s not an accident: Talking nonsense is what you have to do to get anywhere in today’s Republican Party.
Until now ... leading Republicans have generally tried to preserve a facade of respectability, helping the news media to maintain the pretense that it was dealing with a normal political party. What distinguishes Mr. Trump is not so much his positions as it is his lack of interest in maintaining appearances. And it turns out that the party’s base, which demands extremist positions, also prefers those positions delivered straight. Why is anyone surprised?
