Former Massachusetts Gov. Bill Weld looking to challenge Trump in 2020 Republican primary

(CNN) — Former Massachusetts Gov. Bill Weld said he’s launching a presidential exploratory committee to run in 2020 as a Republican.

“I hope to see the Republican Party assume once again the mantle of being the party of Lincoln. It upsets me that our energies as a society are being sapped by the President’s culture of divisiveness in Washington,” he said Friday in New Hampshire. “Because of the many concerns, I’ve established an exploratory committee … as a Republican in the 2020 election.”

Weld was the 2016 vice presidential nominee on the Libertarian Party ticket with former New Mexico Gov. Gary Johnson.

Weld will face an uphill battle in his efforts to take down Trump. History shows that presidents generally only face serious primary challenges when their approval rating within their own party is at 75% or below. Trump is currently far above this threshold.

Trump recently scored an 89% approval rating among Republicans nationally in a Gallup poll. Even in New Hampshire, where Weld is expected to base much of his campaign effort, Trump showed a similarly strongly 83% approval rating with Republicans in a late October University of New Hampshire poll.
