AMID POLL FLAP, CELEBRITIES RUSH FINAL CONTRIBUTIONS TO HARRIS CAMPAIGN. Here’s the terrifying thing about the political debate that has dominated public life for more than a year leading up to today, election eve: Almost everything we say is based on our reading of polls that may or may not be accurate. It could turn out that nearly everyone, no matter what side, was wrong because we were all building narratives on incorrect data. We could at this very moment be standing on the 17th floor of a giant house of cards. And the wind will start blowing Tuesday night.

As is traditional, a bunch of polls came out on Sunday for a final look at the electorate before Election Day, or at least what’s left of Election Day after all the early and mail-in voting. They showed the race between Vice President Kamala Harris and former President Donald Trump virtually tied nationally with perhaps a little progress for Harris in the swing states. But overall, pretty much the same situation we have seen for weeks.
