WATCH: MSNBC pundit equates blocking of election overhaul bill with apartheid

In an interview with MSNBC's The Beat host Ari Melber Tuesday evening, Thompson expressed his frustration with the results of Tuesday’s Senate vote, and apparently had some confusion about how representative apportionments in the Senate is meant to work.

"50 Democrats represent 43 million more people than the 50 Republicans do. And this is a holdover from, really, the time of enslavement," said Thompson. "Many of the Senators represent places that don’t have the same population while the majority of people support this legislation. So this is not a democracy."

"This is a minority that is controlling this and, at the risk of making a controversial metaphor, we know what minority rule is, and there’s a term for minority rule. And that’s called apartheid. We fought against that as well," Thompson continued.

Thompson slammed Senate Republicans for voting against the bill, resulting in a 50-50 split along party lines, failing to meet the required 60 votes to pass.

"A minority of Americans, representing a minority of Americans, is doing all it can to prevent democracy, and from the majority of people in this country voting and we've got to do something about that," said Thompson.

Thompson goes on to say that the fight isn’t over. He and other activists were going to continue "organizing and mobilizing" to fight for "their voting rights."

"That's why we're in these streets. I totally agree with with Senator Schumer, something's going to have to be done," Thompson continued. "We just got to have got to keep organizing and mobilizing people are going to have to continue to vie for their voting rights. So we can have some semblance of democracy in America with what they’re trying to take away."
