"I tuned in [Monday] and there was more white booing than the Casper movie", Meyers quipped.
"I know you are Bernie or Bust, but Bust won", Meyers said on his show.
Noting that Republican rival Donald Trump is now leading Clinton in some national polls, Meyers urged Berners to wake up and smell the demagoguery. Seth Meyer's joined the campaign effort remotely with his Late Night with Seth Meyers segment posted to YouTube on Tuesday. Meyers described Trump as a "racist demagogue" and admonished Sanders supporters who ignored the lessons of history when men like the real estate mogul were elected.

Meyers channeled a message similar to comedian Sarah Silverman's, who, though a Sanders supporter during the primaries, told Bernie-or-busters they were being "ridiculous" while on stage at the convention.
Bernie Sanders has come out and showed support for Hillary Clinton, but his supporters have not exactly gone to Hillary's side. "We've all experienced disappointment", he said. Hell, he couldn't get Rihanna to date him, but he doesn't "stand in the kitchen and boo my wife when she's telling me how she plans to make my life better".
Sanders has attempted to unify the Democratic Party by stating numerous times, including in his speech Monday night, that he is fully endorsing Clinton.
"Bernie did a great job".
The Late Night host also addressed the often-heard line: at the end of day, how many people do YOU know who will actually be voting Trump?
"Bernie did a great job, you did a great job", Meyers concluded, addressing the Bernie supporters. "But also, you have to be quiet now".
