Hey Leif, a liberal here.
I think Trump is a wild card, he has great business experience, but what I've heard of his foreign policy is insane. Also I think he will lack moderate support from both republicans and indepents.
I'd be tempted to vote for Romney, his unstated stance on Healthcare is interesting, but his social policies would probably prevent him from getting my vote, anyone who comes out as being opposed to Gay Marriage is not going to get my vote.
As far as the tea partyers, they are the ones who scare me, half the time the just look stupid, and the other half of the time they look insane. I really feel that they could irreversably devestate the country for years to come due to their detachment from reality. I have some serious problems with the republican party, but before the tea partyers they at least weren't delusional.
Also anyone who says we can solve the debt crises without an increase in taxes is either lying or stupid. No one wants to pay more taxes, but most people don't want to get rid of medicare, medicaid or social security either. I'm very open to reform, but it has to actually be reform, not removal.
