There's a new NYT/CBS poll out that asks the question of whether the ability to Filibuster should be ended. 44% of respondents said the filibuster should remain in place, 50% said it should be removed.

Taken along with Pelosi's comments, there is no reason why Democrats should not feel comfortable with getting rid of the filibuster and pushing through their agenda.
