A good mark might be $60 million. Online bookies poured $32 million so far into the Amendment 2 campaign to legalize sports betting, and a casino company grumpy about the deal countered with $14 million to defeat it.

Winning for Missouri Education, the Amendment 2 campaign funded by DraftKings and FanDuel, has already set a record for the most money donated to a ballot measure campaign. The previous record was $31 million raised by supporters of a 2006 proposal to protect stem cell research.
