A left-wing primary challenger to U.S. Rep. Nancy Pelosi says the House Minority Leader is not as safe as many may think, and she may have a political disruptor named Donald Trump to thank for that.

Bernie Sanders supporter Stephen Jaffe is taking Pelosi on in a primary later this year, and he’s tacking to the left of Pelosi in liberal-friendly San Francisco.

“I don’t think she is quite as untouchable as she might believe and I do believe that in post-Trump universe, that she is vulnerable,” Jaffe told Fox Business’ Charles Paine on Monday.

Jaffe believes Trump’s presidency has helped to fuel left-wing activism, and many of them are opposed to Pelosi, too.

“They don’t like what I will call the Democratic corporate establishment,” Jaffe said.

“Pelosi, (Debbie) Wasserman Schultz, Hillary Clinton faction of the party which just remains firmly entrenched and unwilling to even admit any fault for what happened in the election.”

Jaffe sidestepped the question over whether he’s trying to move the Democratic Party to the left.

“I’m trying to be the representative of the people of San Francisco,” he said. “I think Ms. Pelosi is completely disconnected from the views and wishes of her own constituents.”

He cited single-payer health care as one area where he disagrees with Pelosi.

“That’s a central issue of my campaign,” he said.
