Terms limits would be a beginning, however, aside from that we have to break up the dumb 2 party system..
I don't want to vote for religious freaks or communists.. so i don't vote.. same with most of the country.. most of us don't care to vote because the party lines don't represent us at all.
Make them get elected on narrow issues, have them form coalitions, etc..
