Rep. Joe Courtney (D-CT) ended his hold-out and announced his support for Barack Obama, according to the Hartford Courant.

From the Courant blog:

Though he had said he was going to wait until the last of the primaries was over, Rep. Joe Courtney decided to instead make his pick for a Democratic candidate clear this morning, chosing Sen. Barack Obama.

Courtney's was the only district in Connecticut that was won -- in a narrow margin -- by Sen. Hillary Clinton. So, unlike the rest of the state's congressional delegation, he had held out on a presidential endorsement, leaving himself among the last remaining superdelegates.

His choice this morning, which spokesman Brian Farber said he had come to within the last two days, as Kentucky and Oregon decided their primaries, leaves only one Connecticut superdelegate undecided: Nancy DiNardo, chairwoman of the state Democratic Party.
