it were allowed, and it is not... he cannot even try to sign up to be included as a candidate... the U.S. government AND each state would have to change their candidate registration laws....but... IF
he could run again...
Yes, I am aware of the fact that a US President has only two terms.
Yes. He would win over a Republican.
Why? Because the Republicans have no one to offer.
Even some of the most hard line republicans, such as Ann Coulter, have said that Obama is the only Democrat that they "fear".
On the other hand, many Democrats are tired of Obama and most want H. Clinton so Obama probably wouldn't get past the Democrat Primaries.
I don't take any interest in domestic US politics (believe it or not)... it's only where it effects my interests that I notice it. So, the Reps are not a thing I know much about.
It seems though, from my uninformed outsiders perspective, that they are currently moving towards a hardline right wing position (small government, low taxes on the wealthy, screw the poor because it's their fault there poor etc). It is based on (theoretically), failed ideas like political pragmatism and the trickle down effect - I also suspect a fair whack of greed and self interest as well.
Hopefully, out of this stupidity on the right, there will emerge a new breed of politician that is not intent on upholding a stupid and failed ideology. The right need to learn compassion, and the left need to learn to manage a budget... But, considering that the USA is economically imploding and diving off a cliff taking the rest of us with it, in a sense it does not matter what the right does or does not do. The US is already dead. They are not getting out of the economic hole without a multitude of deaths... anyway...
I can't say I'll miss Obama. I do not agree with the hard right that he is evil. I just think he had an uncanny ability to always pick the worst of any two options. I just put it down to him being a moron rather than malicious... I hope Hillary does better, though I doubt it.
