President Joe Biden calls himself the most pro-union president in history and often touts his humble background, yet he and his party may be drifting further away from winning the support of working-class voters.

Biden has in recent weeks attempted to flip the script on Republicans, saying their agenda will hurt low- and moderate-income voters who didn’t attend college.

“Under this new plan, this tax plan, the ultra-MAGA agenda, while big corporations and billionaires are going to pay nothing more, the working-class folks are going to pay a hell of a lot more,” he said May 4. Biden contrasted that with last year’s American Rescue Plan, which “started to grow the economy from the bottom up and the middle out: rescue checks and tax cuts for working families that gave them just a little bit of breathing room and put food on the table and a roof over their heads.”

But real-world economics and the Democratic Party’s priorities may be sending a different message to voters.

HBO host Bill Maher blasted the left-wing movement to cancel student loans as a losing issue for Democrats that would further erode the party’s stance with the working class.

“We who didn’t go to college and didn’t benefit from that are gonna subsidize you to get your degree in gender studies and sports marketing and all the other bulls***,” Maher said. “I think it’s a loser issue.”

Maher noted that just 13% of people carry federal student loan debt, whereas 65% don’t hold college degrees. Half of all federal student loan debt is held by people seeking graduate degrees.

A Gallup poll released in March showed that Biden had lost support since taking office among voters who never attended college, with his approval rating with the group falling from 52% to 37%. Support slipped among those with postgraduate degrees — but only from 69% to 59%.
