Since President Joe Biden‘s withdrawal from the presidential race on Sunday, 38,500 people, most under 34, have registered to vote on Vote.org, a nonprofit, nonpartisan voting registration technology platform.

The 700% spike in voter registrations for the platform was the largest of the cycle and was higher than when Taylor Swift endorsed Biden in 2020. It is unknown what affiliation most of the registrations counted for, but it is likely that a majority are Democrats, given the timing.
