Bernie Sanders is being called on by supporters to mount another race for the presidency. Soon after Donald Trump was announced as the winner of the 2016 election Tuesday night, Sanders' fans asked him to run again in 2020, according to a report in The Independent.

But Sanders will be 78 then, making it unlikely he will be on the ticket. Sanders ran against Democratic nominee Hillary Clinton in the primaries but lost. The DNC didn't help his cause as they came to "loathe" Sanders' campaign, according to the Nation, and in turn, help get Clinton elected.

Sanders won Wisconsin and Michigan in the primaries, though, and was popular among white working-class voters, a sore spot for Clinton in the general election. Trump took Michigan and Wisconsin and got a majority of his votes from white Americans.

Sanders released a statement Wednesday that said Trump won the election because he "tapped into the anger of a declining middle class that is sick and tired of establishment economics, establishment politics and the establishment media."

Sanders, who ran on the belief the economy should work for everyone, not just the wealthy, said, "People are tired of working longer hours for lower wages, of seeing decent paying jobs go to China and other low-wage countries, of billionaires not paying any federal income taxes, and of not being able to afford a college education for their kids – all while the very rich become much richer."

He said he would work with Trump, but not if he "pursues racist, sexist, xenophobic and anti-environment policies."

Then, Sanders said, "We will vigorously oppose him."
