It's not too late. I just got an email from the ACLU PeoplePower, go to the website to start phone banking now!
From the website:
"We need you help to call as many voters as possible through election day in these key states so that civil rights and civil liberties win on November 6th!
We will provide you with everything you need - a script, training resources, and the means to call voters in these key states, you just need a phone and a computer or tablet. Let’s do this."
