if you had to choose which man has had more consistent ideals over the years - it IS obama.
Granted, most of his ideals involve redistribution of wealth, greater govt control, less freedom, etc. Not good things.
So I think we can agree while obama has been consistently liberal his entire career, Romney was a liberal governor (gun bill, romneycare), but now promises to be less liberal.
We're choosing the promise of less liberal (from romney, who delivered it but promises to stop it) - over Obama, who we KNOW is going to proudly be continually liberal.
Obama wins on consistency, Romney wins on the fact he's promising not to be liberal anymore.
