Yeah, I think Runoff Elections are better than the current system. Problem is, Third Party candidates who can't compete with the big two feel disenfranchised.
Another alternate system that I would like to see in favor of what we currently have is Proportional Representation. If the Green Party miraculously gets 5% of the vote, then they should get 5% of the political positions. I just don't know how this could be implemented, though.......
