A third party is what messed things up here in GA for the Senate. Since our system works on a 50%-plus-one requirement, having three parties means that unless a particular candidate gets enough support, it'll end in a runoff. Which it is this time around.
The special election for the other seat was even more of a clusterfuck 'cause there were at least three parties running and a whole host of nothing candidates who scattered the votes so much that the "winner" only came out with 30-something% of the vote. So how that's gonna end, I don't know.
Party reformation? Yes. A third party to further fuck with the votes in a system that was originally no-party and shifted to a two-party system? No, I don't think that'll work out well.
