TARGETING JOE IN CONNECTICUT…. In 2006, when Joe Lieberman lost the Democratic Senate nomination he claimed he wanted, the senator immediately created something called the Connecticut for Lieberman Party. After the election, the senator lost track of his “party” and made no effort to maintain it.

With that in mind, the Progressive Change Campaign Committee unveiled a new 30-second ad this morning, featuring the chairman of the Connecticut for Lieberman Party, John Mertens, blasting the senator’s obstructionism on a public option as part of health care reform.

“Joe never forgets who he ran to represent: himself,” Mertens tells viewers. After noting that Connecticut voters support a public option, “three to one,” Mertens concludes, “Joe has a message for Democrats, and all the voters who want him to support the public option: it’s not about you; it’s all about Joe.”

Responding to the ad, Lieberman’s spokesperson referred to the public option as part of “the agenda of narrow ideological interest groups.”

It’s an odd thing to say. The ad itself cites a poll showing 68% of Lieberman’s constituents supporting the idea. Are they all members of “narrow ideological interest groups,” or is Lieberman just woefully out of touch?
