Mike Bloomberg spent over $1 billion on his short-lived presidential campaign.
Business Insider reports that's roughly over $23 million for each delegate he won.
Bloomberg spent 20% of that money flooding the country with ads.
He also treated staffers to perks that rival those at Google.
He paid salaries nearly double those at other campaigns.
He gave away free meals, booze, iPhone 11s, and furnished apartments on Manhattan's Upper East Side.
The former New York City mayor also gave his supporters free food, T-shirts, and buttons at rallies.
