Coming off of big wins in the Virgin Islands and Puerto Rico this weekend, the Associated Press reports that Hillary Clinton is within 26 delegates (pledged and super) of clinching the Democratic presidential nomination. With upcoming races on Tuesday in New Jersey, California, Montana, North Dakota, South Dakota and New Mexico, the folks at NBC First Read summarized the situation with pledged delegates like this:

Clinton must win 30% of remaining pledged delegates to get a majority in pledged delegates

Sanders must win 70% of remaining pledged delegates to get a majority in pledged delegates

Based on previous races and current polling, it is likely that Clinton will win New Jersey and New Mexico, while Sanders will prevail in much less delegate-rich Montana, North Dakota, South Dakota. Everyone expects California to be a nail-biter. That’s why this morning Greg Sargent suggests that even a “win” in California won’t save the Sanders campaign. At the end of the day on Tuesday, he will be behind Clinton in the number of pledged delegates and – if you include superdelegates – she will have gone over the threshold of the 2,382 needed to win the nomination. His only play would be to convince a large number of superdelegates to vote against the leader in pledged delegates.

All of this means that Bernie Sanders’ day of reckoning will be this Wednesday. Either he will decide to concede that he has lost the primary, or attempt to disrupt the Democratic Convention in July. According to Peter Nicholas, that is still an unsettled discussion going on within the campaign.

A split is emerging inside the Bernie Sanders campaign over whether the senator should stand down after Tuesday’s election contests and unite behind Democratic front-runner Hillary Clinton, or take the fight all the way to the July party convention and try to pry the nomination from her…

Tad Devine, a senior Sanders strategist who advised Democratic nominees Al Gore in 2000 and John Kerry in 2004, among others, suggested the “path forward” is uncertain, hinging on the outcome in California and other states that have yet to vote. He voiced a conciliatory note, describing how the two campaigns might set aside differences that have grown more pronounced in the heat of the year-long campaign…

Campaign manager Jeff Weaver, who has worked in Mr. Sanders’s congressional offices and Vermont-based campaigns dating to the mid-1980s, takes a more aggressive approach…

“The plan is as the senator has described it: to go forward after Tuesday and keep the campaign going to the convention and make the case to superdelegates that Sen. Sanders is the best chance that Democrats have to beat Trump,” Mr. Weaver said. “The trajectory is the same regardless of the outcome in California.”

Ultimately, the candidate himself will have to make the call. It will be up to Bernie Sanders to decide whether he continues to be a progressive voice within the Democratic Party or sidelines both himself and his supporters as disrupters.
