Nothing? Nothing? Get your head out of the sand, LeGrande.
Obama will split the democratic party and the pubs will do what they do best, retreat. The result will probably be similar to Clintons presidency, except that Democrats will consolidate their positions in Congress.
If McCain wins then all of the liberal goals will get achieved because McCain will have no opposition at all. Everything good that happens will make the Democrats look good and everything bad that happens will be the Republican Presidents fault. Democrats will own Congress for the next 40 years.
If I was a liberal I would certainly vote for McCain. Now if we had a Republican House or Senate, or even a shot at that, then this scenario would be different, but we don't. We have already lost and we are in for a long period of rebuilding.
Do I sound depressed? I am. The fifth column in the Republican party won. I might buy a sailboat, there must be some beautiful unspoiled places left in this world.
