Source: No, Illegal Immigrants Won't Elect HillaryThe argument is interesting, but it’s ultimately quite speculative. Even if one accepts their demographic math, their assertion only works if the 2016 election is extremely close (which is far from a given), and even then there are good reasons to think that these four electoral votes won’t be the sole factor that makes the difference.Uniform Swing – If 2016 Isn’t a Truly a Squeaker, This Doesn’t MatterSo let’s get an obvious fact out of the way: If this election isn’t close, then moving four electoral votes from one side to the other won’t matter. If Sen. John McCain had won four more electoral votes in 2008, he would have still lost, 361-177, to then-Sen. Obama. And if then-Vice President George H.W. Bush had lost four votes to then Massachusetts Gov. Michael Dukakis in 1988, Bush still would have won the Oval Office, 422-115.
