I strongly believe that illegals and non-citizens do vote in substantial numbers - especially in states controlled by the Dems, particularly California which is completely run by the Dems. I was a California voter for a number of years and was always struck by their lackadaisical approach to voting. When I moved to another state, they kept mailing me ballots even when I tried to de-register. I more or less had to force them to de-register me because I would never break the law and vote twice (once in CA and another in my home state). It was clear to me, however, I could have easily done this - probably with no repercussions.
Thus, Hillary’s ridiculously large margin in CA are probably inflated by quite a lot of illegal voting and the California authorities aren’t going to do a thing about it. It really should have a federal investigation.
I’m in soCal. I doesn’t surprise me that illegals vote in Cal, it’s easy for them. What would surprise me is if they didn’t vote. There is no one in office here who would stop them.
