Influence

You can use money to influence an election by paying off certain people with certain skills. For example, in the current presidential race, Obama and Clinton can both pay off super delegates in return for them voting in their favor come July. Although they might have to pay a steep price, some might say its worth it since neither candidate can clinch the nomination with just pledged delegates. I could also give money to lobbyists and others with influence to try and sway more voters' opinions about my candidate.
