Bernie Sanders learned not to mess with fans of "The Bachelorette."

Viewers of the hit ABC dating show took to Twitter to slam the Senator because his speech at the Democratic National Convention ran long, cutting into "The Bachelorette."

"Bachelorette" host Chris Harrison predicted the fans of the ABC dating series would be angry, tweeting "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 was right; Many fans fumed at the Vermont senator.

The "Bachelorette" did come on eventually, but it was about 30 minutes later than usual.
