I've said it before (and yes, I'm going to say it again); Michael Gerson is one of the few columnists of either stripe who can regularly be objective rather than doctrinaire.
His most recent effort, "The Tea Party Risks Scaring Away Voters," is about the ridiculously extreme positions being taken these days by the most ardent tea-party politicos, for example, the demands of Sarah Palin and others to impeach Obama basically because his policies aren't theirs, or the one-shot wonder Chris McDaniel who hoped but failed to replace Mississippi Senator Thad Cochran, making accusations that the election was stolen.
Gerson says these attitudes are self-delusive, and he's right. He says their proponents aren't really "conservatives" in the traditional sense, which is true. He worries that they will scare voters away from Republican candidates.
I suspect he's corrrect on that point too, though I'm less concerned than he is about the effects. Gerson is worried about the next election, when he thinks voters in general, turned off by the shortcomings of the Obama approach, will be taking another look at the GOP, and be turned off. Perhaps so (I hope so!) but my sense is that the tea party has a destiny to fulfill, but the time isn't ripe. We won't restore a healthy two-party system by dissuading them now from taking these wacko positions (as if we could, anyway). Their fate is to make themselves so self-evidently unthinkable that they are utterly repudiated at the polls and fade into oblivion. We may need one more election to do that. Sarah, keep talking.
