I've met Bill Clinton, Obama a couple of times... I certainly didn't meet George Bush, and wouldn't want to.

I think it's just simply not accurate to give Al Gore and Bill Clinton all of the credit for a successful economy, ...

Oh, well, that's just Bill Clinton.

I've met a handful of presidents, from Jimmy Carter to Bill Clinton to George Bush to Barack Obama.
