I prefer Paul to Obama, and I prefer Obama to Romney.
I haven't spent enough time listening to Gary Johnson or any of the other 3rd party guys to know enough about them to support/reject them. Most likely I'd like them just as much as Obama at least, and better than Romney.
Obama's fans and critics seem to largely and willfully ignore that he is largely another Neocon in practice. He's like a more successful, better spoken GWB. There are things that he certainly is not. He's not a socialist. He's basically an acolyte of the hyper-rich wall street people that put him where he is, and he hasn't forgotten that fact. Health Care reform? Nothing more than a collective hand-job to the insurance industry. To hear his critics you'd think he's Satan himself, but the man is just 3.0 in the Bush legacy, whom his critics largely worshipped blindly.
I'm okay with Obama. Romney needs to fail if for no other reason than to force the GOP to kick the wingnuts to the curb. The reason we got Romney, who stands for absolutely nothing at all other than getting elected and probably doing things that only benefit the 1%+ richest americans, is that his opponents were completely fucking insane. Bachmann? Palin? Perry? And so on, who seriously thinks that any of these maniacs and malcontents would be an effective leader, I wouldn't trust any of them with the job of wal-mart greeter.
