Obama's pretty far left on a lot of issues from what I've been able to glean.

As far as McCain's bad temper, I've got a problem with that. I have a bigger problem with Obama's policies.

I presume you've heard that he supports "card check", which means eliminating the secret ballot in union representation elections. That's far enough left that even George McGovern thinks it's wrong.

If you've managed to get to the left of McGovern, I submit that radical might be a good word for it. :)
