There was a study done in 2014 link here into non-citizens voting in 2008 and 2010 and came to the conclusion that there could have been close to 2,5 millions non-citizen voting during those elections.

That number is actually not that high if you factor in the actual Census data based on remittance payments to Mexico, which puts illegal numbers in the US somewhere between 20-30million, not the 11mil based on data from 2010.

Then there's also debate that went down before the election regarding voter ID, somehow it's discriminatory to request this when people come out to vote. Let's not forget that the majority of the Democratic Party supports letting illegals vote.

Lastly the US is not a democracy which is basically mob rule, it is a Constitutional republic. I really don't get why everyone keeps going on about the popular vote?
