Democrats want CO to nominate anybody but Trump, not to nominate nobody.
If CO nominated nobody then the democrats gain nothing; Trump is still nominated by the same percent of delegates, they can't say there's more dissention the party, and they look like anti-democracy crybabies. It's a lose-lose for them.
But if CO (and then GA, CA) went for DeSantis they say the party is divided and Trump is unpopular etc and it's a win-lose for them (dems still look like losers, but also have sullied Trump).
