Freshman Rep. John Boccieri (D-Ohio) will announce his health care vote at a press conference at 10:40 a.m. at the Capitol.

The fact that he's holding a press conference suggests it's a win for the Democratic leadership. It seems unlikely he'd make a big show out of it if he wasn't standing by his party and this bill.

Regardless, this is a big one either way. Boccieri is seen as a pivotal vote, and whichever side nabs him in 85 minutes will hail the decision as proof of their momentum.

Boccieri didn't appear at an event in his state with President Obama this week, but he has said that he's willing to cast a tough vote.
