The Republican Party is putting Bernie Sanders at the center of every 2020 campaign, with senior GOP strategists confident the socialist front-runner for the Democratic nomination is the ticket to a November sweep, whether he is the nominee or not.

More than eight months before Election Day, vulnerable Republican Sen. Martha McSally is up with an advertisement on Arizona television tarring Democratic challenger Mark Kelly as a “Bernie Bro.” It’s a message that Republican strategists are busy replicating in tough contests across the country. Party insiders see Sanders as the perfect antidote to lingering queasiness about President Trump, especially in battlegrounds such as Arizona, where suburban swing voters are poised to decide the outcome.
