Billionaire Warren Buffett is devoting part of Election Day to get-out-the-vote efforts—as he helps drive voters to the polls on a trolley he hired.

The longtime Democrat had promised to help boost turnout at a Hillary Clinton rally in Omaha in August. Buffett says some people have it tougher than others—maybe an illness or trouble with their car. He says he wants to do his part so everyone gets a chance to vote.

More than 100 people have volunteered to help Buffett drive voters to the polls.

Buffett is a supporter of Clinton’s, but on Tuesday he declined to talk about that. Instead, he said he just wanted to encourage everyone to vote regardless of party affiliation.
