On Tuesday night at the Democratic National Convention, a couple hundred Bernie Sanders supporters staged a walkout after their candidate lost the roll-call vote for the presidential nomination. Instead of allowing the delegates’ seats to remain conspicuously empty in prime time, organizers pulled replacements from wherever they could find them, engaging in a seat-filling operation that put the Oscars to shame. (Note to Donald Trump: you could have done this, too.)

Wednesday night’s program was aimed directly at the seat-fillers. After a front-loaded display of progressive values to kick off the convention, Elizabeth Warren and Jeff Merkley and Bernie Sanders were out of the way, and Democrats pivoted from appealing to the progressives in the room, and more to a thin sliver of undecided voters watching at home. And it was a particular type of undecided voter, too.

Put it this way: When convention organizers realized they were running out of time—as it was, Barack Obama didn’t wrap up until 11:45 p.m, well out of the prime-time window—they had to search the rundown of speakers to find someone to bump. Michael Bloomberg, the independent former mayor of New York City, gave his speech. Sherrod Brown, the populist senator from Ohio, didn’t.

Brown’s remarks were handed out to the press beforehand. (The assumption is that he will give them tonight, though that’s not confirmed.) They were about manufacturing, and how to bring economic vibrancy back to middle America, and how to restore the middle class.

It wasn’t that kind of night. Instead, we got Bloomberg, who opened by saying that “many Democrats wrongly blame the private sector for our problems, and they stand in the way of action on education and deficit reduction.” The line was supposed to read “education reform,” incidentally—he swallowed that buzzword, amid a smattering of boos.
