From my friends at Good News Roundup:
Election Protection Hotline: (866) OUR-VOTE -- (866) 687-8683
They rely on a suite of voter helplines: 866-OUR-VOTE (administered by the Lawyers’ Committee for Civil Rights Under Law), 888-Ve-Y-Vota (administered by the NALEO Educational Fund), 844-Yalla-US (Arabic/English) – administered by the Arab American Institute, and 888-API-VOTE administered by APIAVote & Asian Americans Advancing Justice-AAJC) and
Voter protection field programs across the country (both legal – managed by the Lawyers’ Committee, and grassroots – managed by Common Cause)
