Its inability to field strong candidates:
There’s nothing about being conservative, even extremely conservative, that would necessarily generate bad candidates. But it’s a mistake to interpret Tea Partyism as simply about being more conservative than mainstream Republicans. Instead, in practice, it’s basically turned out to be a cross between radicalism for the sake of radicalism, along with an extreme suspicion of elites. Which in turn has made it rather easy for hucksters and scam artists to convince Tea Party voters and activists that solid conservatives are really squishes and RINOs. There are no issue positions one can cling to that will prevent those charges; accusations of being insufficiently “conservative” in this atmosphere, to these voters, are impossible to refute.
Indeed, as we’ve seen with Ted Cruz, the very reaction to crazy things that Tea Party politicians say really is the best proof that they are actually True Conservatives.
Which doesn’t mean that Democrats are about to win a Senate seat in Mississippi (although they would be smart to at least get a plausible candidate on the ballot, just in case). But it does mean that we can expect more of the same from Tea Party candidates – perhaps even worse, since by this cycle, perhaps, raving against rape will be too old hat to get condemned by Rachel Maddow, and therefore not sufficient to establish one’s True Conservative credentials.
