All elections, whether by the people or the Legislature, shall be free and voluntary: and any elector who shall receive any gift or reward for the elector's vote, in meat, drink, moneys or otherwise, shall forfeit the right to elect at that time, and suffer such other penalty as the law shall direct; and any person who shall directly or indirectly give, promise, or bestow, any such rewards to be elected, shall thereby be rendered incapable to serve for the ensuing year, and be subject to such further punishment as the Legislature shall direct.
