Arkansas Rep. Tom Cotton (R-Surrender Caucus)
Conservatives spent the last three weeks they were fighting for the American people, attempting to carry out their will. The polling easily disproved that, of course, but it didn't matter. Two million people signed Sen. Ted Cruz's petition, which is exactly like 314 million Americans supporting them.
So when it finally came time to vote to end the shutdown and threat of national default, it was genuinely interesting to see Reps. Tom Cotton of Arkansas, Shelley Moore Capito of West Virginia, and Steve Daines of Montana vote in the affirmative. All three are either declared or presumed Senate candidates, and all three represent solidly red states.
Not all Republican Senate hopefuls voted yes. In Georgia, where a crowded primary will ultimately crown the most faithful teahadist, none of its congrescritters voted yes. But Cotton, Capito and Daines don't have serious primary opposition to worry about (not yet, at least), thus were able to vote in line with public opinion.
And since public opinion isn't in line with Ted Cruz, they ended up going the smarter direction.
