Re: illegals voting
another state that probably has a problem is my own Minnesota, with almost total lack of legal voter verification, and a sizeable non-citizen population. Anecdotal evidence....I helped register two new voters last fall, and all they had to do was to check a box on a form saying that they were US citizens and eligible to vote, and no proof of anything was needed.
On Election day, 2016, a whole series of radio spots were broadcast encouraging everyone in MN to go vote....saying all anyone needed was either a utility bill showing residency or lacking that, someone to "vouch" for them....not making this up.
And I did google it, and found that Minnesota indeed allows "vouching".
