It's a national matter!
"In 2005, the U.S. Government Accountability Office found that up to 3 percent of the 30,000 individuals called for jury duty from voter registration rolls over a two-year period in just one U.S. district court were not U.S. citizens.[1]
While that may not seem like many, just 3 percent of registered voters would have been more than enough to provide the winning presidential vote margin in Florida in 2000.
Indeed, the Census Bureau estimates that there are over a million illegal aliens in Florida,[2] and the U.S. Department of Justice (DOJ) has prosecuted more non-citizen voting cases in Florida than in any other state.[3]
Florida is not unique. Thousands of non-citizens are registered to vote in some states, and tens if not hundreds of thousands in total may be present on the voter rolls nationwide.
These numbers are significant: Local elections are often decided by only a handful of votes, and even national elections have likely been within the margin of the number of non-citizens illegally registered to vote.
Yet there is no reliable method to determine the number of non-citizens registered or actually voting because most laws to ensure that only citizens vote are ignored, are inadequate, or are systematically undermined by government officials.
Those who ignore the implications of non-citizen registration and voting either are willfully blind to the problem or may actually favor this form of illegal voting......"
