Gingrich isn't going to be and shouldn't be a candidate for all the reasons you and others state. That doesn't mean he should be relegated to some think tank. He would be a great RNC chairman because he would be involved in tactics, which is where, I think, he can shine.
What we need is someone in his or her forties who can debate and communicate with depth and style. We can't run a blank slate; by 2012, Obama will be well-defined, whether by crafting or by actions he took because circumstances required he take them. We have to run someone against what he is at that point, someone who can provide a solid option--conservatism that is demonstrably better than what he offers/offered.
Not sure who that is. But I don't think it's Sarah Palin.
We NEED a guy who has been TESTED... and that’s Newt
Agreed.
