Democrats in New Jersey want to make sure the state does not enact strict new voter ID laws that they say could lead to suppression at the polls.
Assembly members John McKeon and Mila Jasey are holding a press conference in Essex County on Thursday to speak against the laws already enacted in 33 states that require voters to produce identification before voting.
A judge this week refused to block a Pennsylvania law requiring voters to show photo ID at the ballot box while the case is being appealed.
Opponents say many voters lack acceptable identification and will be turned away. They argue the effort could hurt President Obama because the laws are likely to apply disproportionately to the urban Democratic base.
Proponents say they are guarding against voter fraud.
