How about:
A) 1r) MHS2002 vs. 2d) Gabu
B) 2r) Mr. Hobbes vs. 1d) Hughento
C) 3r) Bullmoose88 vs. 4d) Nation
D) 4r) WMS vs. 3d) ThePrezMex
then, after the four races, the winners of A) and B) have a round off, and the losers of A) and B) play the winners or C) and D); with the losers of C) and D) eliminated.
So, for example:
MHS2002 defeats Hughento
Gabu defeats Mr. Hobbes
Nation defeats Bullmoose88
WMS defeats ThePrezMex
ThePrezMex and Bullmoose are eliminated, MHS2002 and Gabu are through to the semi-final.
Hughento then plays the winner of C), depending on the result. If the GOPper wins, then thats the race he runs in, but if it's a democrat, he and the democrat who won C) will both play against a slightly harder generic GOPper, who is all SR instead of all R. The best totals for both hm and the Democrtic winner of C) are compared, and the one witrh the better total goes through. This is the same if there is too GOPpers, and also for races B) and D).
After this, you'd have MHS2002, Gabu, and, presuming they won, Hughento and Mr. Hobbes in the semi finals. Here, the Democrats play the GOPpers each 2 times, once with Dynamism and once without, and the best of the two groups go through to the final. If there is only one democrat left, then the three GOPpers play them 45 times each, and the Democrat goes straight through to the final anyway. This is the same if there is only one GOPper left, obviously.
Thn, the final is the best D versus the best R, in a best 7 match tournament, first to 4 winning.
Complex, but fair, imho
