where i live (USA), i don't think it matters either way. both of the leading parties are elitist and back corporate and banking interests over popular interests, so i think both republicans and democrats would hold similar positions towards BTC.
fortunately, i think the political establishment already understands that it's too late to ban BTC.
meh, "free and fair" elections are overrated. like i said, we supposedly have them in the USA, but the average citizen here is completely disenfranchised from the political decisions that affect their lives.
