Does anyone have figures available on past US Presidential elections showing how much each candidate spent? I have a vague feeling that, historically, the candidate spending the most has usually won, but I would like some numbers to verify this.
Historically, campaigns have opted into public funding. So, at least in the first analysis, there hasn’t been any difference in spending between candidates.
Of course there’s spending by political parties and outside groups and spending before the convention to account for. And the occasional eccentric billionaire funding their own campaigns, so a more complete answer to your question is probably possible, but we’ll probably need some agreement on what spending to count.
