Three reasons...
(1) New York and California have the most foreign born residents in the country.
Why would anyone risk committing felony voter fraud in those two states when almost every elective office will be won by a Democrat anyway?
(2) Texas and Florida have the next largest number of foreign born residents.
However, the Republican Party has a very powerful presence in both those states.
Why would Republicans in those two states just calmly stand around and watch millions of non-citizens and criminals vote in their elections?
(3) Also, if voter fraud is so easy to get away with, how do we know that Trump didn't win Wisconsin, Michigan, and Pennsylvania with voter fraud?
1) Many don’t know, so they ask. And as the videos showed, they are often told it’s fine to vote, citizen or not.
2) Republicans in red states are SEVERELY CONSTRAINED by federal laws and court rulings. One of my kids has been out of the house for several years, and re-registered in his new place immediately. Guess who’s name was still on the rolls right on top of mine (and he was in town during early voting, would have been very easy).
3) Republicans don’t generally break the law as they have MUCH MORE to lose (including assets, credit rating, future jobs, etc.). Dems not so much, felons not at all.
Also much of the fraud is in proxy voting where poll workers wait until the polls are closed, and then start voting for people...which is why late results in close races ALWAYS favor Dems, strongly.
As it is, what we think doesn’t matter - we’ll have national Voter ID in 4 years and regardless of who’s right, it won’t matter...elections will be clean.
