The 2013 survey by John McLaughlin found 13 percent of non-citizen Hispanics admitted they were registered to vote.
Just based on that survey where 13% of non-citizen Hispanics admitted they were registered to vote, it may be extrapolated that:
61,000,000 x .13 = 7,930,000 Non-Citizens could have potentially voted in the last election. And that percentage was based on those who admitted to being registered.
The pro-immigration control Center for Immigration Studies analysis released Monday finds that 45.3 million legally reside in the United States.
"Our best estimate is that in 2015 there were 5.1 million children with at least one illegal immigrant parent," he writes.
"Taken together, the best available evidence indicates that there were a total of 15.7 million illegal immigrants and their U.S.-born children in the adjusted December 2015 CPS, accounting for 25.7 percent of the 61 million immigrants and their children in the country."
