If you're not a citizen of the United States, you are not allowed to vote. If you're dead, you're not allowed to vote. If you move, you're not allowed to vote at your old address.

Florida wants to clean up its messy voter rolls, filled with problems like those. The Feds protested, claiming it would "disenfranchise" some voters, their favorite catch-all that requires no proof. Now they have changed their minds. CNS News reports:

In a victory for Republicans, the federal government has agreed to let Florida use a law enforcement database to challenge people's right to vote if they are suspected of not being U.S. citizens.

The agreement, made in a letter to Florida Gov. Rick Scott's administration that was obtained by The Associated Press, grants the state access to a list of resident noncitizens maintained by the Homeland Security Department. The Obama administration had denied Florida's request for months but relented after a judge ruled in the state's favor in a related voter-purge matter.

Voting rights groups, while acknowledging that noncitizens have no right to vote, have expressed alarm about using such data for a purpose not originally intended: purging voter lists of ineligible people. They also say voter purges less than four months before a presidential election might leave insufficient time to correct mistakes stemming from faulty data or other problems.
