Senator Joe Lieberman's gradual drift to the Republican side of the aisle continues apace today as the party confirms that the Connecticut independent will speak at the Republican National Convention. It's not much of a surprise: Lieberman, a staunch defender of Israel, has been a long-term member of the Senate's mainly Republican "If You Don't Bend Over And Take It From The President You're Not Serious About The War On Terror" caucus. The former Democratic vice-presidential nominee is particularly bitter about the 2006 primary challenge that knocked him from his party's ballot, and he's well aware that Senate Dems are only allowing him to keep his committee chairmanships because they're hamstrung by a narrow majority; if, as expected, the party sees major gains this cycle, he's probably done for.
With John McCain sweetening the pot by putting it about that he's seriously considering Lieberman as a running mate (although I personally think that's just a headfake to try to get Barack Obama to do something stupid like picking Chuck Hagel), why shouldn't Joe go all the way around and join the GOP? Sure, the party doesn't want for moralizing, self-righteous pricks, but at least Joe would be one of the few circumcised ones.
