While he is a very smart man, he is charismatically challenged and, like Obama, takes forever to get his point across.
I strongly perfer Sarah Palin, but should she chose not to run, my choices would be Thune, DeMint or Pence. Of all the names being tossed around, Mitt would be my last choice.
His parents weren’t both US citizens when he was born, so by the definition intended when it was written into the constitution, he wasn’t ‘natural born’.
But you’re right, he’s charisma challenged, and I like your backup list—likewise with Romney excluded.
