Idaho Democratic Party Chairman Keith Roark, currently uncommitted, will endorse a presidential candidate at a press conference in Boise at about 2 p.m. ET, the state party confirms. The party was mum on who he'd endorse, but at least one Idaho blog's speculation is he'd be for Obama. Obama won the state's caucus overwhelmingly, 80%-17%. Obama netted 12 delegates in the state, which the Obama campaign famously touted as a larger gain than Clinton got out of New Jersey. Clinton netted 11 out of the Garden State.
