This could be very big. Rep. Jason Altmire (D., Penn.) has done his darndest to position himself as the deciding vote on health-care reform, and I predicted earlier this week that he would end up voting with the majority either way.

Congressman Jason Altmire will vote against the latest version of health care reform when the U.S. House of Representatives votes on the bill this weekend.
Altmire confirmed that he has decided to vote no in a telephone conversation with KDKA political editor Jon Delano.
The McCandless Democrat is expected to post a statement on his website later today.
In a live interview on KDKA-TV News at 6 on Tuesday, Altmire said his constituents would help him make the final decision.
“I’m deciding it by doing everything I possibly can to hear what they have to say,” he said. “The rallies at my office, the phone calls, emails, and letters that are coming in to Washington and in the district.”
Altmire voted against the House health care plan last November.

But again, who knows! Rep. Allen Boyd (D., Fla.) has just gone no-to-yes! And he’s co-chair of the Blue Dogs!
