House Democrats on Tuesday introduced legislation that would essentially nullify many of the state-based voter ID requirements that Republican legislatures have enacted in the name of fighting election fraud.

While supporters of those requirements argue they’re needed to ensure the integrity of elections, critics, including a long list of congressional Democrats, contend the changes are actually built to discourage seniors, minorities and other vulnerable populations from voting at all.

Under the bill authored by Rep. Rick Larsen (D-Wash.), voters in states with government ID requirements could sign an affidavit attesting to their identity in lieu of showing the mandated documents.
