Apparently he was a Goldwater booster back in college. That's usually a pretty good sign, since the same Ruling Class turds who tried to derail Reagan had it in for Goldwater before him.
I like what I've heard of him so far. I also particularly like that he's not "another damn Senator" throwing his name in the hat. Of all the selection pools for President, the US Senate has to be about the worst possible choice. The mentality of a Senator is far different from what is needed in the Chief Executive. There are of course some exceptions (Goldwater?) but generally Senators are the sort who have this smug appreciation for the vaunted collegiality of that chamber, the Republican ones at least. Out of all the RINOs out there, it seems the worst ones are in the Senate.
John McCain. Bob Dole. Do we really want to go that route again? Just Say No to presidential contenders from the Senate!
