The party rules have done away with winner-take-all contests, setting a threshold of 15 percent of the vote in congressional districts and statewide. A big spending, targeted effort could pick up hundreds of delegates in those venues.

That might enhance the long-shot chance that no one goes into the Milwaukee convention next July with anywhere near a majority. Under that scenario, the dream of every political journalist, there’s a brokered convention.

The Democrats wouldn’t turn to Mike Bloomberg, but he’d have a chunk of pledged delegates that could help shape the outcome. His top priorities, other than being president, are to thwart Warren and defeat Trump.
