Mayor Bill de Blasio has enlisted Senator Bernie Sanders's help to bolster his populist cred, showing New Yorkers that even high-profile politicians can spend their Monday morning waiting for a delayed, overcrowded subway train.

Sanders, who will host a campaign event with de Blasio at Terminal 5 this evening, is also expected to endorse the mayor's millionaire's (MIEL-YON-AYERS) tax to fix the subway. As you may recall, de Blasio belatedly endorsed Clinton in the primary, before eventually telling the press that Bernie Would Have Won.

The fundraising event comes one week before a very sleepy mayoral election, which de Blasio is expected to win in a landslide. In other election news, the 2016 primary will never, ever, ever end:

[UPDATE 12:40 p.m.] From the platform of the Fulton Street and Broadway station, Senator Bernie Sanders endorsed the mayor's millionaire's plan to fund the MTA, and acknowledged that us New Yorkers have "got a real problem here when it comes to the subway." Flanked by union groups, supportive local politicians, and the mayor, Sanders noted that it's "not a radical idea to say that when you ride on the subway, you should ride in comfort, you should ride in a subway car where you can sit, where you know when the train is coming."

De Blasio also channeled the country's most popular politician, referring to nearby Wall Street as the home of the "millionaires and billionaires who dominate this nation," and framing his proposal as "another way of responding to the inequality that plagues our society." If approved by state lawmakers, the plan would bring in approximately $820 million annually by the year 2022 through a .5 percent increase in income tax on individuals who make over $500,000 and married couples who make more than $1 million.

The mayor also reiterated his line that congestion pricing, recently endorsed by Governor Cuomo, is a regressive tax. Asked where he stood on that proposal, Sanders said he didn't want to get involved in state politics.

Sanders will join de Blasio for a campaign rally at Terminal 5 at 7 p.m. on Monday. Tickets to the event, free with RSVP, are still available.
