The person you're looking for is Joe Lieberman. He took that 60th vote away which kept the filibuster going.

Congratulations!

This won't do what you want. We'd still have unlimited money in politics, we'd still have hyper powerful lobbyist influence, and we'd have far more ignorant Congress folks for both to corrupt. Term limits are a non-starter until we get the other issues squared away and Democrats in the House passed massive election bills last session. Unfortunately, the Senate is broken by Mitch so that's fun.
