60 in 2010

Sabato looks at the Senate balance and the 2010 election.

But that's about the only good news for Republicans in the early Senate going. Remarkably, even after losing six net Senate seats in 2006 and another seven or eight (pending the Minnesota resolution) in 2008, the GOP still has more seats up (19) than Democrats (17) in 2010. (There will be a big reversal in 2012, with 24 Democratic seats to only 9 Republican ones-but that's getting too far ahead of the story.)

In 2012, the wheel swings back. The 2010 Republican Senators were last elected on Bush's 2004 coattails. The 2012 Senators were last elected in the 2006 Dem year.
