But raising a ton of money is not a guarantee of success, as Jeb Bush (and his massive super PAC) can attest. Bush spent a ton of money to finish sixth, fourth and fourth in the first three Republican contests. While Trump, who enjoys the ability to get media coverage every time he opens his mouth, spent relatively little.
Notice, too, that this excludes money spent by super PACs. If we included the $100 million-plus spent by Bush's, Right to Rise, he'd be far and away the winner on most-spent-per-vote. But that waste of cash isn't his fault, and let's face it: Guy is already having a bad 24 hours.
Correction: Due to a calculating error, this article originally excluded votes accrued in South Carolina in the money-per-vote calculus, which is obviously a big mistake. The figures have been corrected. I apologize for the error.
