To my younger (American) followers:

Even if the polls are ridiculous you still have to vote
Even if the experts say it’s over you still have to vote
Even if the newscasters have called your state you still have to vote

Elections are decided by the people who show up on election day. All the polls in the world don’t mater if you don’t go into the booth and make a choice. All the experts can be (and frequently are) wrong if you don’t go into the booth and make a choice. News media tend to call stats at 5% of votes tallied. If your polls are still open, you can still change things.

Don’t let a strong summer showing in the media dissuade you. You still have to show up in November. It does matter. If people see their candidate winning and decide that they don’t have to show up and be heard, there is a chance the other side will rally. You have to participate. No matter what.
