Something as simple as name all nine supreme court justices, your U.S. representative, and two Senators, would be enough that the D's would never draw more than 20% of the vote.
And that's considering the fact that D's would be out front of every polling place handing out the answers.
I would settle for proof of citizenship, and proof that your alive at this point (plenty of dead vote here in Illinois, all democrat too it seems).
I was at the DMV a few weeks ago, and the lady asked “you want to sign up for motor voter?” I wanted to change from republican to independent, so I filled out the paperwork which consisted of 3 questions: a) party affiliation, b) do you reside in Cook County and c) are you a US Citizen.
I asked the gal “how do you know I’m a citizen?” Her reply “cuz you marked it on the form”
In Illinois, that is all you need to become a registered voter I guess. Just mark the questionnaire.
That is why they want the Illegals here I guess.
