I'm not advocating this (quite yet), but if we throw out the bad republicans, and there are a bunch of democrats elected, then in 2 years for the house, and 6 for the senate, there will be OPEN PRIMARIES on our side, where we can run people who will do what is RIGHT.
And we'll have all the incentive to work twice as hard to throw the democrats out of office and replace them.
A lot of times the only way to get rid of an incumbent is to get the voted out in a general election. It's VERY hard to defeat them in primaries, they have the reigns of party power, the money, and the votes of all those who believe better a dead republican than a live democrat.
So you are presuming we can make it through under Dem rule. Post 9/11, I'm not very confident of that.
