Richard Spencer made headlines when he announced he's voting the Democratic ticket in November.

Spencer famously endorsed President Donald Trump in the 2016 elections. But he says he's switching tickets because he believes Biden is a bigger racist than Trump.

"I plan to vote for Biden and a straight democratic ticket. It's not based on "accelerationism" or anything like that; the liberals are clearly more competent people," Spencer tweeted on Sunday.

Biden's camp hastily rejected Spencer's endorsement.

"When Joe Biden says we are in a battle for the soul of our nation against vile forces of hate who have come crawling out from under rocks, you are the epitome of what he means. What you stand for is absolutely repugnant. Your support is 10,000% percent unwelcome here," Biden's campaign tweeted.

Biden, 77, helped author the Violent Crime Control and Law Enforcement Act that later became known as the 1994 crime bill.

Biden oversaw the Senate Judiciary Committee at the time. The bill was signed into law by former President Bill Clinton in 1994.

Many Black males were incarcerated under the 1994 crime bill. Biden's running mate, California Senator Kamala Harris, was a prosecutor who locked up more Black males than her predecessor.

Together, Biden and Harris have locked up more Black people than any presidential candidates in history.
