As I said before the 2011 midterms had much more at stake for Democrats than just losing congress and the senate. Via The Hill:

“For the first time in two cycles, Democrats will have more seats up for grabs than the Republicans, and the party could see its shrunken majority erased altogether.

Several of the senators up for reelection came in on the 2006 Democratic wave, when the party picked up six GOP seats and won control of the chamber.

Sens. Bob Casey Jr. (D-Pa.), Claire McCaskill (D-Mo.), Sherrod Brown (D-Ohio), Sheldon Whitehouse (D-R.I.), Jon Tester (D-Mont.) and Jim Webb (D-Va.) defeated GOP incumbents that year but will have to win reelection in 2012.

And two senators who won special elections Tuesday, Joe Manchin (D-W.Va.) and Kirsten Gillibrand (N.Y.), will face voters again in two years.

Democrats lost at least six Senate seats Tuesday, with results in Washington and Alaska undetermined as of press time, but they retained control.

That could change in two years, when Democrats have 21 seats up for grabs, compared to only 10 for Republicans. Also up for reelection are Sens. Joe Lieberman (Conn.) and Bernie Sanders (Vt.), the two Independents who caucus with Democrats — meaning the party has a total of 23 seats to defend.

“The numbers are really working against them, no question about it,” said Jennifer Duffy, a senior Senate analyst at The Cook Political Report. “It will come down to what it always comes down to: retirements and recruiting.”

As before the GOP won key governorships in Ohio, Florida, Pennsylvannia, Tex, all of which along with other states will undergo redistricting. Couple this with a CNN poll today that found that prospective GOP candidates for President in 2012, with the exception of Sarah Palin could defeat Barack Obama.
