That’s how Hillary Clinton won the popular vote, by illegal alien voters in Los Angeles County ALONE! Get rid of that crap and guess what, Trump not only won the election in 2016 but he won the popular vote as well
Another factor in liberal strongholds like CA, is that conservatives stay home, thinking their vote doesn’t really matter. This results in lost house seats and local elections, as well as further tilting the “popular vote”. Sure, the same thing happens in Red states, but not due to the fraud of voting by the illegal and the dead.
