They need 51 to change the filibuster rules and so far cannot get that many of their 55 or 56 to agree.
I believe they will get that number because, as evidenced by the Obamacare vote, the dems are not afraid to take advantage of their majority status while Republicans usually are.
33 seats were up, 23 held by Dems, and 6 of them in open Dem seats.
And the GOP manages to lose two seats. This was not due to Romney — he ran well ahead of nearly all senate GOP candidates in all senate races from coast to coast.
Hispanics and young people are a huge problem.
