Chicago congressman Dan Lipinski is backing U.S. Sen. Barack Obama's presidential bid.
Lipinski had been one of the two remaining holdouts among Democratic superdelegates in Illinois' congressional delegation. He says he's endorsed Obama because of the candidate's emphasis on overcoming partisanship and uniting the country.
It may not be entirely unexpected; it's also not yet included in Politico's Superdelegate Count either.

The attacks by the Clinton campaign, which makes the pitch that she is the most electable Democratic candidate because of her success in large states with primaries, risks alienating lawmakers and other superdelegates who are expected to determine the outcome of the nomination battle.
In interviews, a host of superdelegates supportive of the caucus system pushed back against that criticism, and said the attacks reflect hardball tactics by a Clinton campaign trying to diminish Obama’s overwhelming success in caucus states.
Rep. Bruce Braley (D-Iowa), an uncommitted superdelegate whose state and district were won by Obama, said the Clinton campaign’s attack on the caucus system is a "cause for concern" in evaluating her candidacy and one of a number of factors he’ll consider in making his endorsement
"The first thing I would say to any national leader, whoever they are, is, ‘Don’t boss around states and tell them how to select their delegates,’ " said Rep. Rick Larsen (D-Wash.), who, like Braley, has not picked a candidate to support in the race
Sen. Amy Klobuchar (D-Minn.), who is uncommitted in the race, said the process has its pluses and minuses, and added that Obama’s strong win in her state’s caucuses was "very impressive and will be a significant factor" in awarding her endorsement.
