Well no. The article you posted, which doesn't provide any data or source to any actual study, just says some researchers EXTRAPOLATED polling data, and they themselves say it is NOT plausible for non-citizen votes to account for all of Clinton's margin.
So not only is this hardly anything to base a conclusion off of, the conclusion that is arrived at is that Clinton still won the popular vote.
Focusing on voter fraud after winning is a weird tack to take, especially when the president has a 36% approval rating, so many people would enjoy a revote.
