The only person who can legitimately call himself a "Bernie bro" cast his vote in the Democratic primary on Tuesday.

Larry Sanders, 84, is the older brother of presidential candidate Sen. Bernie Sanders, 78. He cast his ballot at the University of Oxford in the UK, the country where he has lived for the past five decades.

"I think a victory for Bernard will cheer people up here in Oxford and around the world, and I think we have a better chance for peace with him in the White House," Sanders told the Oxford Mail.

Sanders, who also works in politics as the health spokesman for the UK Green Party, defended his brother's democratic-socialist beliefs, saying "if you look at the actual policies, they're very mainstream."

When asked if he would move back to the US if his brother won the presidency, Sanders said he would be "tempted to visit a lot" but wouldn't move because he has children and grandchildren in the UK and works there.

"I'm proud of my work," Sanders said. "Bernard's doing a little bit better, but we're in the same field."

Sanders has always been a big supporter of his little brother Bernie. At the Democratic convention in 2016, where Hillary Clinton won the party's nomination, there was a heartfelt moment when Larry Sanders cast the final delegate vote for his brother, representing Democrats Abroad primary voters. He started to tear up as he spoke about how proud their parents would be of Bernie for his accomplishments and his efforts to help the working class.
