Advisers to President Trump say Joe Biden is the Democrat he most fears running against, and that Pennsylvania is the state he worries most about flipping against him.
Trump’s calculation is based partly on how weak he sees other Democratic possibilities, including Bernie Sanders or Elizabeth Warren, and partly on who’s capable of appealing to his base of working class whites.
Trump advisers say says Biden, like the president, conveys authenticity, is comfortable in his own skin, can work a crowd, and relishes throwing and returning punches. Biden could — and would — needle Trump, and get under his skin, with a brio that few other big-name Democrats could muster.
Biden will be 77 in November 2020, Trump will be 74.
