"Study supports Trump: 5.7 million non-citizens may have cast illegal votes
By Rowan Scarborough - The Washington Times - Monday, June 19, 2017
A research group in New Jersey has taken a fresh look at post-election polling data and concluded that the number of non-citizens voting illegally in U.S. elections is likely far greater than previous estimates.
As many as 5.7 million noncitizens may have voted in the 2008 election, which put Barack Obama in the White House.
The research organization Just Facts, a widely cited, independent think tank led by self-described conservatives and libertarians, revealed its number-crunching in a report on national immigration.
Just Facts President James D. Agresti and his team looked at data from an extensive Harvard/YouGov study that every two years questions a sample size of tens of thousands of voters. Some acknowledge they are non-citizens and are thus ineligible to vote.
Just Facts’ conclusions confront both sides in the illegal voting debate: those who say it happens a lot and those who say the problem nonexistent."

With that many illegals (non-citizens) voting in 2008, more than that voted illegally in 2016 as there were millions more who came here illegally and voted.
