Could be, but he was/is/always will be the least of Americans' worries on Capitol Hill.
All he's done to make all Republicans hate him is lose (even though he actually won) a presidential race, helped make the internet into a commercial entity, and make a movie about climate change. I haven't seen the movie so I can't say one way or the other whether it's bullshit or not, but the consensus seems to be that while he hit on something significant, he oversimplified the solution for it. That said, most of his detractors about the film have been well-to-do business owners and CEOs...not surprisingly the same people who would lose the most to see aggressive actions taken to combat climate change.
Al Gore may be a dullard and if you want to stretch things maybe a bit of a shady salesman, but there are waaaaaaayyyy worse people in Washington.
