How many more terms do you think there will be a Democrat on the presidential post?

It would honestly surprise me if we would see a Republican on the presidential post after the display of clownish characters like Ron Paul, Sarah Palin, Donald Trump, Michelle Bachmann, etc, on the political field lately. I mean, the world is already launching buckets of ridicule at the U.S. for the absurdity of their conservatives - even my highly Christian and very conservative mother (we live in Sweden) thinks that they are ludicrous, not to mention selfish, especially for wanting to repeal the healthcare reform. This ought to breed a larger body of voters for the Democratic Party in the next election, and considering the deep-seated insanity they've displayed in the last years - for many, many elections ahead.
