He's been a Republican for a gazillion years. There's a reason for that.
They will eat him up and spit him out unless he wins the primaries. Then he will be their savior.
There is no honesty in politics, sadly.
As much as I'd love to see that, they will never - ever - let it happen. Ron Paul wants to undo essentially everything that they, and their co-conspirators on the 'other side of the aisle' have built up for themselves. Democracy is a nice talking point, but there's no way the Republicrats will give up power voluntarily.
