So how to produce a candidate? A savvy tea party would assess politicians with resumes sufficient to become president, court and flatter known quantities like Mitch Daniels, who would fundraise well be acceptable to other constituencies in the Republican Party, and work to ensure that the longshots it elevated were principled guys like Gary Johnson, who've proven their ability to govern should they improbably catch fire in the course of campaigning around the nation.

But the actual tea party isn't savvy. It overestimates its clout within the GOP, fails to appreciate the many obstacles to winning a general election, let alone implementing its agenda, and is therefore careless and immature in choosing its champions. It elevates polarizing figures of questionable competence like Sarah Palin because doing so is cathartic. It backed Michele Bachmann despite her thin resume, erratic behavior in interviews, and the fact that she cares most about advancing a socially conservative agenda, not a small-government agenda. Its erstwhile favorite, Rick Perry, doesn't even subscribe to what ought to be a core tea party tenet: that the government shouldn't subsidize particular firms, picking winners and losers. Perry is a right-wing corporatist. And Herman Cain, the front-runner of the week? He has zero governing experience, acknowledges that he knows next to nothing about foreign policy, flip flops on matters of tremendous consequence, and touts a flawed economic plan, 9-9-9, that could never pass.

What do all these dubious champions have in common? Their red meat rhetoric and ability to antagonize liberals. What many tea partiers share is a belief that the best way to get where the country should be going is by being more ruthless than the Democrats; by fighting them zealously in the media, zinging them from the stump, and never, ever compromising with them in Congress or at the White House negotiating table. This is partly a reaction to George W. Bush's tenure, when tea partiers believe they were sold out by a big-spending, big-government RINO who kept compromising with Ted Kennedy. It is partly a reaction to the perception that they tried nominating media darling and "maverick" John McCain in 2008, and he lost. It is partly a reaction to the belief, stoked by talk radio, that every compromise with liberals is just one more ratchet in the direction of socialism, and that a confident, uncompromising conservative, in what they imagine to be the model of Ronald Reagan, is the solution to their woes.

Their approach has several flaws.

1) Bombast isn't a predictor of fealty to principle. It's just strategically uttered rhetoric, like everything else said by politicians, a profession where what is promised on the campaign trail always deviates from what is done in office. How odd that the most cynical voters are most taken by extravagant promises of loyalty.
