Delegate update: One for Clinton

From NBC's Domenico Montanaro
This morning we reported on the superdelegate switch of Joe Andrew for Obama. But First Read has confirmed that Clinton is expected to pick up one today as well -- John Olsen, president of the Connecticut AFL-CIO. The Hartford Courant first reported it this morning. Olsen will hold a 2 p.m. news conference at the state capitol to announce the endorsement, per a Connecticut AFL-CIO source.

Yesterday, Clinton got the backing of another state AFL-CIO president, Bill George of Pennsylvania.

To the count...
SUPERDELEGATES: Clinton 268-248
PLEDGED: Obama 1,490-1,334
OVERALL: 1,738-1,602

*** UPDATE *** First Read is aware of the three potential Illinois add-ons, who are for Obama (Daley, Currie, Stroger). We are not adding them into Obama's count as yet, since they will be officially named after the state convention on Monday.
