Ironically they are very simliar. For example, he got the driver license for illegal immigrants law repealed, just like Davis nuked that proposal several times before he turned Kamikaze in a desperate drive for votes and "changed" his mind.
Yes, they are similar.
The main difference they have, is that he might have a lot of power to influence the legislators, since he's still riding on the popularity of the last election. Where Davis had just scant party affiliation to help him, this guy has popular support behind him. It already failed him in this vote, but he can always go back to the voters to pressure the legislature.
The question is how long that influence over the voters will last, if he doesn't get results quick, it's going to erode as fast as Ventura's support dissapeared into a black hole.
