Whatever arises in place of the Republican Party as we know it today will not advocate Trickle Down Economics any longer. You can see them TRYING to pretend like they're not for it now- McCain saying he wants tax relief for everyone, not just the uber rich. But of course he's lying.
I would kind of like for there to be a second viable party, since absolute power corrupts absolutely, blah blah blah and all that rot. But right now the Republican party is such a shitty, looked down upon brand name that only the far, far right nutbars are going to be left after this election to pick up the pieces. And they'll think that they lost so badly this year because they didn't go FAR ENOUGH to the right. The Republicans are in such a pickle because they like to ostensibly play to the "look down your nose at snooty, uppity educated folk" card. Well guess what? When you do that, people getting educations say "well shit, they're not for me then I guess." So you end up with a party of Sarah Palins. And that will only appeal to other Sarah Palins, who thankfully are becoming a smaller percentage of the population. So that's a losing strategy over the long haul, as is the "fuck over the non-white skinned people" kick that Republicans have been on for a while.
I know that people say that a third party or more system wouldn't work in our bicameral legislature having, checks n' balances system. But I kind of think that if you had to have a majority coalition cobbled together to get things passed, it would encourage active and actual bipartisanship for the sake of the country and progress as opposed to the toxic insanity that we have today. We could have a far left party (that's me), the boring centrists (that's APF), the conservatives (toxic adam and sd) and then the loony religious nutbars. Obviously the libertopians would be right out. Now, the loony religious nutbars would probably win in some states, but since by nature they won't want to compromise on anything none of their agenda would get advanced and eventually their constituents would have to ask themselves- "hey, we don't get money for bridges and shit so much. maybe we should try electing someone that isn't insane." Or at least it would be hoped.
Anyway, just a thought.
