Bernie Sanders supporters took to Twitter to voice their anger as the Democratic presidential nominee announced his official endorsement of Hillary Clinton for president.

It seems that some supporters at the rally even ripped up and discarded some of their pro-Bernie merchandise:

There’s bound to be many Bernie supporters upset over his decision to endorse Hillary Clinton. Some have agreed that voting Trump is the best way to get back at Clinton and the Democratic party that they believe has betrayed their “political revolution.”

Some have suggested that Sanders’ actions may have handed Trump the election. With Clinton’s disapproval rating rising by the day, they may be right.
