There are a lot of dim bulbs in the Senate, and there’s a lot of competition for the dimmest (Patty Murray, Babs Boxer, Jim Jeffords, Susan Collins come immediately to mind, and I’m sure that there are others), but my impression from every interview with him that I’ve ever heard is that Lincoln Chafee is not qualified (in Jonah Goldberg’s famous quip) to be a spell checker in an M&M factory. The Conways have a roundup of his political prospects this fall, including some other oatmeal-brained commentary from him:

Laffey described Chafee’s views on the region as “two standard deviations outside of American and Rhode Island thought.” In an effort to make the point, he quoted Chafee’s own words questioning the legitimacy of what the senator termed American “gripes” with Iran’s nuclear program…Chafee, he said, “doesn’t get it at all” that “there are some really bad people in the world.”

They’re upset that the National Republican Senatorial Committee continues to support him against the much more conservative Laffey, presumably on the assumption that he’s the only Republican (to the infinitesimal degree that he is) that can win Rhode Island. But here’s where the dim bulbedness comes into play. According to them, if even with the support of the NRSC, he loses the nomination, he’ll run as an independent.

But that would seem to me to result in a Republican win, because an independent (and liberal) Chafee would split the liberal vote with the Democrat candidate, whereas the Republicans would coalesce around Laffey. So this really is a fight worth waging, and it not only doesn’t necessarily risk a Senate seat for Republicans, but it might be an opportunity to replace Chafee with a real Republican, and provide a lesson to the other RINOs.
