DNC threatens to sue North Carolina elections board over plan to purge 100,000 voters

Potential lawsuit follows vote by the board to require additional registration information from voters in a perennial battleground state

The Democratic National Committee is threatening to sue the North Carolina board of elections if they go forward with plans to purge almost 100,000 voters from the rolls.

The state elections board - with a new Republican majority - voted at its 24 June meeting to require registered voters to cast provisional ballots if they have not provided their driver's license number, last four digits of their social security number or an identification number supplied by the state.
