"Paying someone to get me elected" is just a political campaign hiring a campaign manager and staff. I don't think that counts as bribery, but it is paying them in monopoly money, aka shares in a long bet that will never pay out.

Yes, this creates an incentive for them to vote for you, but those 20 votes aren't going to win you the election. A similar incentive exists if you are hired by any political campaign; if they win you maybe get a job in their staff.
