Dumb gets old quick, according to a recent CNN/Gallup/USA Today poll. The better we know the Tea Party, the less we like it. Here’s how those surveyed rated the movement that gave us Minnesota Rep. Michele Bachmann, Florida Gov. Rick Scott, former Alaska partial-term Gov. Sarah Palin, and Kentucky Sen. Rand Paul, among others:

Favorable: 32%
Unfavorable: 47%
Never Heard Of: 7%
No Opinion: 14%

Nate Silver at FiveThirtyEight took these results and combined them with earlier polls to show a trend tea baggers can’t deny. With each passing day, their approval numbers go down, down, down.

Silver concludes that Republicans, who scored 44% favorable and 48% unfavorable in the same CNN poll, have the most to lose if the tea baggers get dunked.

I’ve long been of the view that the Tea Party, despite nominating poor candidates in a couple of key races, was a significant net positive for the G.O.P. in 2010, both because it contributed to the “enthusiasm gap” and because it helped an unpopular Republican Party to re-brand itself in never-out-of-style conservative draping. But if the Tea Party ain’t over yet, the point in time at which it was an electoral asset for Republicans soon may be.
