" Some analysts have suggested the polls could even be understating support for Harris."
Were I on Harris' election team I would totally be encouraging that.
The Democrats as a group are largely from low turnout demographics. It's easy to get them to stay home. Keep everyone on the edge of their seats.
I honestly believe that Trump's victory in 2016 was a result of Democratic apathy. Polls consistently showed Clinton way out in front. As a result, enough voters in swing states, Wisconsin and Michigan and Pennsylvania, stayed home or made some protest vote to result in a Trump presidency. Writing in Bernie Sanders was a vote for Trump.
I'd rather the Democrats didn't make that mistake again.
