Not sure the Republicans have a TR in the party. They might have a handful of guys who keep posters or placards of some of his more famous quotes on or behind their desks, but that's about it. I don't really see too many democratic versions either. Is there anyone with serious popular backing advocating either heavy regulation or dismantling of the too big to fail institutions (Fannie and Freddie included)? Maybe Kucinich or Ron Paul, but neither of them is going to find themselves a bullet away from the White House and Ron Paul is certainly no Teddy Roosevelt.

If I recall correctly in at least one of those instances, Clinton was faced with a bill passed by a veto proof majority. He still could have vetoed it, but the effort would have been wasted.
