A lot of what needs to be done is making sure that the Harris win is large enough that you can’t easily claim that a handful of ballots should be tossed and change the outcome. That means:
- Check your voter registration — part of the Republican strategy has long been invalidating registrations so people can’t vote
- Volunteer — nothing in the world quite like talking to people.
- Donate — money is used for everything from ads to voter turnout operations
- Organize; be prepared to turn out with others in your community to actively object to any effort to ignore your votes
There’s prediction markets and bookies making odds as well. People putting money on the line are probably a little more accurate than polls by themselves. Looks like people think the odds currently favor Harris, but not by a large margin. 50.9% chance for Harris and 47.1% for Trump (https://www.forbes.com/sites/siladityaray/2024/08/09/harris-has-vaulted-past-trump-as-the-bookies-favorite-to-win-presidential-election/). IIRC, prediction markets significantly favored Clinton in 2016 right before the results came back though.
