It’s way too early to know how the November elections will go. The shift from Biden to (presumably) Harris and its impact on voting is hard to predict.
What I can say with confidence is this: Young voter participation will go up significantly, particularly among young women. My daughters are seeing MANY friends who were unlikely to vote before but likely to vote now.
My daughter - who will be a first-time voter this year - just now came to me asking for help figuring out how to register. She will be part of the flood of young voters casting their ballot for Harris.
