IDIOT: I wish I lived in a swing state. Not only would Obama and Romney actually care about my vote, my vote would count! My vote has been written off by the media and the two major presidential campaigns. I voted third party! I voted against the status-quo and for real change!
ME: Well aren't you special! Now, if you want to do something which could actually lead to real change, support amending the Constitution so that we have proportional representation like they have in many other countries, where voting for a third or fourth or fifth or sixth party is not throwing your vote away.
IDIOT: How would that weaken the two party system? You think for one moment the two parties will do anything to help third parties? Every time congress passes a law about campaign finances or elections, it's for one reason and one reason only: protect incumbents! If you vote democrat or republican, you're just enabling the status quo, voting for more dead soldiers, and voting for fewer civil liberties!
At this point I considered giving up, but I gave it one more try:
ME: Seriously, how would proportional representation weaken the two-party system? It would completely do away with the two party system.
IDIOT: How so? Would the two parties still control the debates? Would they still control how money is spent on campaigns? Would incumbents still get free mailings?
It's depressing. Some things are so simple that I don't know how to explain them. I don't have the patience to be a teacher of morons.
