If Rep. Nathan Deal (R-GA) does in fact step down from his House seat today to focus on his run for Georgia governor, House Speaker Nancy Pelosi (D) will find it offsets one of the Democratic votes she's already lost on the health care reform bill.
Though the bill received 220 votes in November, Democrats have lost four supporters of the bill since then: Rep. Joseph Cao (R-LA) says he no longer supports it, Rep. John Murtha (D-PA) passed away and Reps. Robert Wexler (D-FL) and Neil Abercrombie (D-FL) resigned to focus on other opportunities.
Deal opposed the health care bill. His potential resignation gives Pelosi a little breathing room.
