US Senate Elections 2012

The 2012 cycle is substantially different than the 2010 cycle which is posted here.

While 2010 cycle has slightly more pubs up than dems - 19 to 17 (including special elections for Obama, Biden, and Kennedy) - the 2012 cycle will feature just 9 pubs but 24 dems (including Lieberman and Sanders).

The keys seems to be to hold ground - at worst - in 2010. A majority can come back in 2012 to the Republican party.

Here's the data:
