The Bernanke Whip Count: 45-20

Update I: Sen. Ben Cardin (D-MD) announced his intention to vote for Bernanke in a statement released this morning. Update II: Sen. Tom Harkin (D-IA) announced this p.m. that he will vote against Bernanke's reconfirmation, while Sen. Amy Klobuchar (D-MN) will vote yes. Update III: Sen. John Ensign (R-NV) said this afternoon he has lost faith in Bernanke and will vote against him.

The clock on Fed chief Ben Bernanke's first term is running down, but Senate leaders have yet to schedule a vote on his reconfirmation. Still, with just a few days left before Bernanke's term ends on Sunday, momentum appears on his side.

On Monday, aides to several Dem senators told Hotline OnCall their bosses would vote for Bernanke's confirmation, while just one -- Sen. John McCain (R-AZ) -- formally announced he would oppose Bernanke.

Countering McCain, Sens. Paul Kirk (D-MA), Kay Hagan (D-NC), Bill Nelson (D-FL) and Ben Nelson (D-NE) all told us they would vote for Bernanke, while Sens. Debbie Stabenow (D-MI) and Barbara Mikulski (D-MD) said they are leaning toward voting yes.

The latest tally shows 45 senators committed or leaning toward voting in favor, while 20 have said they will vote no. Senate rules dictate Bernanke must have 60 supporters to make it to a second term.

But 35 senators remain uncommitted, and many have said they are concerned about Bernanke's record during his first years in office.

The WH and Senate leaders have expressed confidence they will have the votes they need. Still, underscoring the trouble some members have with Bernanke's renomination, even the top GOPer in the Senate, Mitch McConnell, has refused to disclose how he would vote.

What was supposed to be an easy confirmation became more difficult recently as populist anger has surged across the nation. It has even cost Bernanke a certain vote; Sen. Sherrod Brown (D-OH) voted for Bernanke when his nomination came before the Banking Committee, but Brown has said he is rethinking that vote.

There is little ideological harmony in those who have said they will vote for Bernanke. They include 12 GOPers, ranging from conservative Sens. Mike Johanns (R-NE) and Richard Burr (R-NC) to more centrist Sens. George Voinovich (R-OH) and Lindsey Graham (R-SC). Dems backing Bernanke include liberals like John Kerry (D-RI) and Chris Dodd (D-CT) and centrists Mark Warner (D-VA) and Evan Bayh (D-IN). Sen. Joe Lieberman (I-CT) will also back Bernanke.

Too, the ideological gaps among those opposed to Bernanke are just as large. Sens. Jim Bunning (R-KY) and Jim DeMint (R-SC) have joined Sens. Bernie Sanders (I-VT) and Russ Feingold (D-WI) in voicing opposition.

No vote has been scheduled yet. Bernanke's term expires on Sunday.
