Bernie Sanders is pushing hard for Alyssa Milano’s endorsement

Alyssa Milano arrived in Miami ahead of Wednesday night’s first Democratic presidential primary debate – and Sen. Bernie Sanders is aggressively seeking her endorsement, The Post has learned.

Sanders has personally phoned Milano several times in recent weeks in a bid win her backing, a source close to “Charmed” actress said.

“Of all the Democratic candidates, the one pounding down her door the hardest is Bernie Sanders,” the source said.

Milano recently said she was “playing the field” of the 20-plus Democratic contenders, despite her friendship with former vice president and front runner Joe Biden.

“To be honest with you, I really feel like I’m dating a lot of people right now,” she told Sirius XM’s “Press Pool” show last week.

“I feel like I’m playing the field and I’m dating, and once I know who’s going to be right for me I will make that decision.”

Milano is expected to attend the back-to-back debates that will be aired live by NBC, MSNBC and Telemundo, and streamed on their apps, at 9 p.m. Eastern time on Wednesday and Thursday.

On Wednesday morning, Milano attempted to tour the “Homestead” shelter in Miami that’s being used to house 2,300 migrant children, but said she was told by the Department of Homeland Security that she needed to seek permission two weeks in advance.

“Of course, you know, in those two weeks they have the time to clean up that place so that is why it was important to just let me in,” she said in a video posted on Twitter.

Reps for Milano and Sanders didn’t immediately respond to requests for comment.
