Bernie Sanders felt the bern from #BachelorNation Monday night.

Fans of “The Bachelorette” blasted the Vermont senator on Twitter after his speech at the Democratic National Convention disrupted the two-hour broadcast.

While east coast viewers got to enjoy all 120 minutes of JoJo Fletcher in her indecisive glory, host Chris Harrison warned audiences the convention could affect telecasts.

“Check local listings cause I’m guessing the #DNC will hijack up #TheBachelorette time in many cities. Some things are even out of my control,” Harrison tweeted.

Though fans finally got to watch the episode 30 minutes later, many weren’t thrilled about missing the all-important rose ceremony following last week’s cliffhanger.

Fletcher narrowed down her remaining four finalists to two on Monday night, sending home fan-favorites Luke and Chase. With Robby and the polarizing Jordan Rodgers the last two men standing, only one will receive the final rose during next week’s season finale.
