Lieberman seems to be genuinely baffled and indeed petulant that his fellow Democrats won't let him have it both ways: To say he is a strong Democrat with a largely progressive record and to work hand-in-glove with the White House to denigrate his own long-suffering and battered party....

At least let's stop pretending that this is a battle for the soul of the Democratic Party. That is far too elevated an enterprise. This is really about the consequences of Lieberman wanting to have his cake and eat it, too.

Can we please put to rest the idea that Ned Lamont’s challenge to Senator Lieberman is a product of, or a wholly-owned subsidiary of, that thing called "the netroots."...

The plausibility of the Lamont campaign is attributable to two major things, none of which have anything to do with Markos Moulitsas or his loyal minions:

1. Decades of statewide progressive organizing in the state. Lamont’s campaign manager is no blogger, but Tom Swan, who left his job as head of the Connecticut Citizen Action Group (CCAG) to run the campaign. ...

2. The fact that Lieberman has run, so far, the second most embarrassingly bad campaign of the year. (The worst campaign’s entire staff just quit [Katherine Harris], so there may be an opening to move up.)

This being one of the highest profile primary elections of the year (if not the highest profile), I think that it’s reasonable to expect the same fine-tooth-comb scrutiny of Senator Lieberman's finances and fundraising reports as there will be of Ned Lamont's.
