Florida Governor Rick Scott (R) has ordered the state to purge all “non-citizens” from the voting rolls prior to November’s election. But that list compiled by the Scott administration is so riddled with errors that, in Miami-Dade County alone, hundreds of US citizens are being told they are ineligible to vote, ThinkProgress has learned exlusively.

According to data from the Miami-Dade County Supervisor of Elections obtained by ThinkProgress:

— 1638 people in Miami-Dade County were flagged by the state as “non-citizens” and sent letters informing them that they were ineligible to vote.

— Of that group, 359 people have subsquently provided the county with proof of citizenship.

— Another 26 people were identified as U.S. citizens directly by the county.

— The bulk of the remaining 1200 people have simply not responded yet to a letter sent to them by the Supervisor of Elections.

You can see a similar letter sent to alleged “non-citizens” by the Broward County Supervisor of Elections HERE. (“The Supervisor of Elections… has received information that you are not a citizen of the United States.”) If recipients of the letter do not respond within 30 days — a deadline that is mere days away — they will be summarily removed from the voting rolls. The voters purged from the list, election officials tell ThinkProgress, will inevitably include fully eligible Florida voters.
