Josh Shapiro, the Democratic nominee for governor in Pennsylvania, has a substantial lead in the polls over his GOP opponent, Doug Mastriano. But he’s leaving nothing to chance in the race against the “uniquely dangerous” Mastriano, a state senator who was outside the U.S. Capitol on Jan. 6, 2021, wants to overhaul Pennsylvania elections and has been accused of elevating antisemitism.

NBC News joined Shapiro for the first leg of a barnstorming six-day, 25-stop bus tour of the state, where he is warning voters about how much is on the line and calling Mastriano “by far the most extreme and dangerous person to ever run for public office in Pennsylvania.”
