What about this guy?
Thaddeus McCotter weighing White House bid - Jonathan Martin - POLITICO.com
Eight years in Congress (including a leadership position), solidly conservative on most issues, voted against TARP, enough of an outsider to make his fellow Congresspeople uncomfortable with him. And he seems pretty smart, and funny to boot. Nobody knows who he is now (I just heard of him today), but that could change at any moment. He seems more exciting than the poor choices we have now. If he officially joins the race I'm keeping an eye on him.
