Make them Filibuster for REAL!!!
I haven't seen this discussed too much so it's time to say it... If Democrats want to turn the tide, they have to make the Republicans filibuster in the old school way! Pennsylvania Governor Ed Rendell agrees. CLICK HERE
Bring a popular bill to the floor that Republicans oppose... ie. Banking Regulations, child care tax credit expansion, pre-existing conditions ban... and make them talk day & night about their opposition. If it goes on long enough, the media will HAVE to pay attention, and what they'll see is the party of no doing what they do best. Even if Harry Reid decides to give in first, it will show the American people exactly what the Dems have been contending with over the last year, and it will frame the Dems as the populists.
This is also the right thing to do if you seriously want to take a crack at changing the filibuster rule. Engage in a multi-day-week debate on the floor over something popular in order to show how broken the system is.
The best case scenario is that you may weaken the will of the GOP in the Senate to constantly filibuster. If they decide to eventually give in on one issue, you can threaten to use the same tactic the next time something important and politically popular comes to the floor.
