President Donald Trump’s Thursday evening rally in Manchester, N.H., is ostensibly about ginning up support for his reelection campaign.

But the state’s establishment GOP class is worried he’ll use the event to do something else: Talk up Corey Lewandowski’s potential 2020 Senate bid.

Republican Gov. Chris Sununu has relayed concerns about Trump’s controversial former campaign manager to party leadership. Tom Rath, a former New Hampshire attorney general and a prominent Republican in the state, says he’s “not a Corey fan.” Former GOP Sen. Judd Gregg took to the pages of New Hampshire’s biggest newspaper to deride Lewandowski as a “thug.”

And Dave Carney, a longtime New Hampshire-based strategist who’s worked on an array of statewide Republican campaigns, called the idea of a Lewandowski candidacy a “joke.”
