Winner: Federalist Party, for running strong races in 4 regions, winning 2 Senate seats (including one where the Fed nominee was so strong Labor didn't even challenge), and an overwhelming triumph of their endorsed ticket/a ticket containing a Federalist/a center-right ticket/a ticket of two blue avatars.
Runner-up: Labor Party, for emerging from a fractured convention to run a competent electoral bid, while defending vulnerable incumbents in two regions, picking up a third, and running a very strong and credible challenger in a fourth, while continuing to advocate a broad, detailed, agenda of reform.
Loser: Federalist Party, for lacking the party discipline to prevent one of its members from attacking the official ticket and launching a write-in bid, endorsing an independent instead of their own candidate (32% of Federalists voted for someone else in the first round), and failing to pickup two Senate seats that were clearly within their grasp (especially if Presidential votes translated to the regional level - Duke won all regions over the Labor candidate).
Runner-up: Labor Party, for failing to put forwards a credible candidate for President (no offense to the Dr, but his campaign was rather seat-of-the-pants and only came to be after the convention), in its absence failing to even get a left-winger elected, whatever the hell went on in that convention (were the choices at one point really Snowstalker and drj?), and failing to win the turnout battle despite an extremely experienced and solid candidate in the Mideast.
This is some great analysis on the elections.
