On March 9, Bart Stupak told The Weekly Standard the following (emphasis mine):

Michigan Democrat Bart Stupak said yesterday at a townhall in his home state, “I’m more optimistic than I was a week ago” that a deal could be reached to pass a health care bill that bans public funding of abortion. Some speculated that this meant Stupak was ready to cave. “Obviously they don?t know me,” Stupak said in an interview this afternoon with THE WEEKLY STANDARD. “If I didn?t” cave in November, “why would I do it now after all the crap I?ve been through?”

Stupak affirmed that he will not settle for an agreement to pass the bill now and fix the bill’s problems on abortion later: “If they say ‘we?ll give you a letter saying we’ll take care of this later,’ that?s not acceptable because later never comes.”
