The trouble is that it's inherently never going to be a hot button topic for the winner.
Whomever wins the election, using the electoral college, will put electoral reform on the bottom of the priority list. Catch-22.
I've said for some time now, I'd vote for a candidate who ran on a single issue: total reform of the voting process. Republican. Democrat. Whatever. The system needs updating and until that happens the rest is just side-effects.
