In order of preference:
Santorum, Gingrich, Perry.
Santorum is right on the issues and speaks well.
Gingrich is like the above, but has age issues. and some problems personally.
Perry is best ideologically, but an ineffective speaker.
Wish we had somebody with Santorum’s persona, Gingrich’s mind and debating ability, and Perry’s position philosophically.
But the IMPORTANT thing is ANY of them are LIGHT-YEARS ahead of the ObamaBastard. If Obama makes the campaign argument about their foibles, he wins. If they make the campaign argument about his mismanagement and treachery, they win. Simple as that.
Perry is preferable to Gingrich on social security and environment issues.
