With formerly undecided Sens. Ben Nelson, D-Neb., and John McCain, R-Ariz., announcing today that they intend to vote yes and no, respectively, on Sonia Sotomayor's confirmation, a vote close to the party line is becoming increasingly likely.

But don't tell the White House, where the buzzword "bipartisan" has adhered to Sotomayor's confirmation, seemingly out of habit. Press secretary Robert Gibbs even cited Sotomayor's nomination as an example of bipartisanship on Friday.

Asked in a press briefing about President Obama's reliance on Democrats in office, Gibbs reeled off some examples of bipartisanship in the capital -- beginning with the Supreme Court nominee. "Well, I mean, I think if you look at -- I think you've seen Republicans come out for Judge Sotomayor," he said.

During another briefing on Thursday, Gibbs took questions directly on the small amount of GOP support. His word choice then was less positive and more dismissive, instead focusing on her judicial experience.

"Without getting into whether or not we're disappointed, I think the president believes, rightly, as many have said, Democrat and Republican, that this is a judge with a tremendous amount of legal experience as a prosecutor, as a judge on two different levels of federal court; somebody who has that very background that is eminently qualified to serve as a justice on the U.S. Supreme Court and hopes that she's evaluated that way," Gibbs said.

Only six out of the Senate's 40 Republicans have said they will vote for Sotomayor. If all the rest vote no and all Democrats vote yes, the final tally would be 64-34 (ailing Democratic Sens. Edward Kennedy of Massachusetts and Robert Byrd of West Virginia aren't expected to vote).

Even if a few Democrats vote no or another Republican or two vote yes, this is shaping up to be a second straight mostly party-line Supreme Court vote, following Samuel Alito's 58-42 confirmation in 2006. Only four Democrats voted for President George W. Bush's nominee; one Republican voted against him.
