The Washington Post reports:
The Biden campaign is warning supporters not to let the Democrat’s sizable national polling advantage over Trump lull them into a false sense of security that the race is over. In a memo, Biden campaign manager Jen O’Malley Dillon urged supporters to “campaign like we’re trailing.” “We cannot become complacent because the very searing truth is that Donald Trump can still win this race, and every indication we have shows that this thing is going to come down to the wire,” Dillon wrote.
Dillon encouraged supporters to use 2016 as a reminder that polling can be wrong and that it all comes down to who can secure the 270 electoral votes needed to win the presidency. While Hillary Clinton won the popular vote in 2016, reflecting national polls, Trump won an electoral college victory by winning several Midwestern states. In key battleground states, Dillon wrote, the “race is far closer than some of the punditry we’re seeing on Twitter and on TV would suggest.”
