Even more than wanting a Democrat to get elected in the fall, I too want change. Obama has held himself out as the candidate for change (we've all heard that before in past campaigns). But you won't effect change by making obseisances to the Republicans. You have to fight them. The Republicans are more than ready for the fight--they have so much to lose--but I don't think Obama is. He just wants everybody to get along and have hope. I think it's very naive.
If he gets the nomination, he'll have to toughen up. And if he wins the presidency, he'll have to toughen up even more to push his programs through Congress and bring about the change he stands for. We'll see whether he can transform his rhetoric of change into reality. I'm surely hoping for it.
