Jennifer Horn, former chair of the Republican Party of New Hampshire and co-founder of The Lincoln Project, spoke to Boston Public Radio Friday about the future of the Republican Party, post-Trump.

Horn recently left the Republican Party and registered as an Independent.

"It wasn't because of Donald Trump, it was because of everyone else," she said. "The Republican Party had an opportunity when Donald Trump lost to cut loose, to look forward and say, 'Let's put this horror behind us, let's put country over Donald Trump, let's do the right thing and try to get back to some level of integrity,'" she said.

But instead, after the election, Republican leaders embraced the idea of a rigged election and advanced lies and conspiracies, Horn said.

"The Mitch McConnells, the Kevin McCarthys, the Marco Rubios became engaged in a full-frontal coordinated assault on democracy in America," she said. "They have made a conscious decision to build the future of the party on the most damaging things that Donald Trump brought to our country."

Can the Republican Party be rebuilt? Not really, Horn said.

"And certainly not by the people that are there now," she said. "The only way there can be a legitimate influential future for the Republican Party is for them to fully denounce everything about Trump and to acknowledge the role that they played in it."
