Brown's Unpredictability Makes Him 'Go-To' Figure

It made no difference, but Massachusetts Sen. Scott Brown and most other Republicans were in the minority Thursday as the Senate voted 63-37 to confirm former Harvard Law School Dean Elena Kagan to the U.S. Supreme Court.

Sen. John Kerry voted in support of her nomination. Brown called Kagan "brilliant," but said he could not support her because she has no judicial experience.

Brown's vote was the latest on which observers were unsure which way he would go, as he didn't make it known until a few hours before the vote.

Mike Allen, the chief political correspondent for Politico, joined WBUR Friday morning to talk about Brown's place in the Senate.
