It’s hard not to get the sense that Joe Lieberman is just taunting Dems at this point. Lieberman doesn’t want to just burn the bridge to the ground, he wants to pour salt in the earth around the wreckage.

Wednesday, Lieberman joined a conference call coordinated by a right-wing House member to bash Barack Obama. Yesterday, he announced the creation of what he calls a “new grassroots organization,” called, “Citizens for McCain.” From the letter the McCain campaign distributed today (no link available):

Citizens for McCain is an organization within the McCain campaign for people who put country before political party and support the candidate for President who has a proven record of bipartisanship. As you know, I caucus with the Democrats as a United States Senator and was the Democrat Party’s nominee for Vice-President of the United States against President Bush and Vice President Cheney. But first and foremost, I am an American. I have an obligation to do what I think is best for our nation regardless of political party.

A couple of things. First, how far gone is Lieberman? In his letter to “fellow McCain supporters,” he uses the far-right, grammatically-wrong construction: “Democrat Party.” Pathetic.

Second, Lieberman calls Citizens for McCain a “new grassroots organization.” It isn’t. In fact, by all appearances, it’s not an organization at all — it’s just a gimmick of the McCain campaign, cooked up to collect money and addresses. Campaigns come up with these gimmicks all the time, but for a sitting senator to announce that he’s the “chair” of a “new grassroots organization,” when there is no actual organization, is pretty ridiculous.

Maybe Obama needs to back him up against another wall.
