We, you, I and the rest of the general public will know in good time, namely when the votes are tallied. Between then and now, we need only ourselves resolve to vote, ideally for anyone other than Trump, and implore and abet everyone we know to do the same.
If you have some quantity, however, great or small, of resources (time, money or both), some ways to do that include:
- contribute to help voters get registered,
- help people in low voter turnout areas to get registered,
- help people in low turnout areas actually get to and from polling places,
- solicit employers to accord PTO to their staff for taking time to vote,
- host a fundraising event,
- solicit employers to coordinate a "go to the polls and vote" event for employees,
- contribute to volunteer shuttle services for people who need rides to polling places,
- give people rides yourself,
- get your friends to do the same.
Those and other things like it are what folks need to do. Respective candidates' political strategy teams are who need to worry about the "mood of the country,"
and that is something they are both well paid to do and quite capable of doing, by comparison, at levels of accuracy making the stuff we get on the news seem like little more than fortune telling.
