Suddenly he’s Prog Joe?

Democratic presidential frontrunner Joe Biden announced that he will adopt plans from 2020 rivals senators Bernie Sanders and Elizabeth Warren in an effort to join forces with the progressive wing of the party ahead of the general election.

In a series of tweets Sunday, the former vice president said that “after consideration,” he was adding a plan from each of the senators to his campaign platform.

“Bernie has put forward a plan that would make public colleges and universities free for families whose income is below $125,000,” Biden wrote. “It’s a good idea, and after consideration, I am proud to add it to my platform.”

The College-for-all act, as Sanders referred to the plan in 2017 when introducing it in the Senate, is a major upgrade from Biden’s original proposal of making community colleges free for everyone for the first two years.

In a follow up tweet, Biden courted Warren supporters with an official endorsement of her bankruptcy proposal.

“Few people in the country understand how bankruptcy hurts working families more than Elizabeth Warren. Today, I am fully endorsing and adopting her bankruptcy plan, which she called ‘Fixing Our Bankruptcy System to Give People a Second Chance,’” he wrote.

Biden’s campaign gave Warren’s team a heads-up on the policy endorsement beforehand, according to the New York Times. His team, however, did not reach out to Sanders’ camp ahead of their endorsement of his education proposal.

A spokesperson for the Sanders campaign told The Post of Biden’s policy endorsement, “It’s great that Joe Biden is now supporting a position that was in the Democratic platform four years ago. Now we have to go much further.

“We need to make all public universities, colleges and trade schools tuition-free for everyone like our high schools are. We need to cancel all student debt. And we can fund it with a small tax on Wall Street speculation.”
