how much, again?

There seems to be some confusion as to how much money Michael Bloomberg actually spent on his abortive campaign to become the Democrat nominee for president in the 2020 election. The sources I saw said $700 million; other sources apparently put the figure closer to $500 million. In the end, it's egregious either way, but for what it's worth, here are some sources that confirm the figure I had quoted.

ADDENDUM: this Instapundit post asks the same question I did: how on earth could someone like Bloomberg have made his billions given the fiscal incompetence we saw on display during his campaign?
