Are the Republican candidates for president this bad?

Worse - and that's without Sarah Palin in the race so far. Time's Joe Klein minces no words:

This is my 10th presidential campaign, Lord help me. I have never before seen such a bunch of vile, desperate-to-please, shameless, embarrassing losers coagulated under a single party's banner. They are the most compelling argument I've seen against American exceptionalism. Even Tim Pawlenty, a decent governor, can't let a day go by without some bilious nonsense escaping his lizard brain. And, as Greg Sargent makes clear, Mitt Romney has wandered a long way from courage. There are those who say, cynically, if this is the dim-witted freak show the Republicans want to present in 2012, so be it. I disagree. One of them could get elected. You never know. Mick Huckabee, the front-runner if you can believe it, might have to negotiate a trade agreement, or a defense treaty, with the Indonesian President some day. Newt might have to discuss very delicate matters of national security with the President of Pakistan. And so I plead, as an unflinching American patriot--please Mitch Daniels, please Jeb Bush, please run. I may not agree with you on most things, but I respect you. And you seem to respect yourselves enough not to behave like public clowns.
