“When you’re teaching audiences to do something they’re not familiar with, like voting by mail, it takes more time and it takes more touches,” said Tatenda Musapatike, senior director of campaigns at ACRONYM, a digital-focused Democratic group that is running an eight-figure campaign to register and mobilize voters in eight battleground states. “More touches means more money.”…

The Biden campaign and the DNC say their efforts are already well underway, and they have already reached out to millions of voters in battleground states to push Democrats to request their mail ballots now. Priorities USA, the Democratic super PAC, is spending $24 million on voter mobilization, which includes vote-by-mail education. Fair Fight, a group founded by Stacey Abrams, has rolled out voter protection programs in 17 states.

“Vote by mail just moves the timeline up. States normally go into [get-out-the-vote mode] a few days before the election, but now in almost every state in the country, we are moving that timeline up incredibly quickly and it’s fast approaching,” said Jenn Ridder, Biden’s national states director.
