100k at the lowest; enough to settle my debts and have enough leftover to invest and get my life on track.
I think I'd charge about the same either way, give or take some, but in the latter case where you can buy and sell votes, it kind of starts to jack with the price. If everyone is selling their vote, then either everyone is going to try and demand a million dollars with it, or eventually none of their votes will be worth anything at all. In group situations, how can anyone vote be worth more than someone else's if they all have equal standing once they're in the ballot box? There would essentially be fixed prices on everybody's vote, the only way it would go up and down is, as you say, during key elections, and that's as an entire group.
