We find that some non-citizens participate in U.S. elections, and that this participation has been large enough to change meaningful election outcomes including Electoral College votes, and Congressional elections. Non-citizen votes likely gave Senate Democrats the pivotal 60th vote needed to overcome filibusters in order to pass health care reform and other Obama administration priorities in the 111th Congress.The study was done by Jesse T. Richman and colleagues at Old Dominion University. The survey size was 32,000 in 2008 and 55,000 in 2010, very large samples.
What can be done to stop the outrage that is non-citizen voting?
