Alice Ollstein for Think Progress:

Republicans in Missouri have been trying to pass a voter ID bill for more than a decade, and they may soon claim victory.

This week, a supermajority of lawmakers sent a bill to the desk of Gov. Jay Nixon (D). Even if the governor vetoes, as he did to a similar one in 2011, lawmakers may have the votes to override it.

Democrats in the state Senate staged an all-night filibuster last week to stop the ID bill, but backed down after striking a compromise deal with Republicans.

The deal involves amendments to the bill that progressive lawmakers say will “ensure no voter is denied his or her Constitutional right to vote.” For instance, the state would be required to provide free photo IDs and any underlying documents necessary to obtain them, such as birth certificates and Social Security cards. Additionally, voters who are unable to get the required ID for whatever reason would be able to sign a legally-binding affidavit promising they are who they say they are, and could then vote with regular ballots.
