FEC filings show Michael Bloomberg spent $1.22 billion on his unsuccessful campaign to win the Democratic nomination.
This is great proof that the influence of money in politics is vastly over-rated. It can help around the margins, but it is no silver bullet.
He received 2.45 million votes in the primaries so each primary vote cost him $499. Staggering.
But the real contest is to win 1,991 delegates to cinch the nomination. He won just 55 so each delegate cost him $22.2 million!
Of course he is worth $55 billion so in one sense he only spent 2% of his fortune. It would be like someone worth $1 million spending $20,000!
