I can check my past voting record in NC.
Re: “I can check my past voting record in NC.”
Since 1980?
I doubt it. Unless you mean what your Party was and when you voted.
Here in Seattle, we can review our voted ballots on the web, but only for about the last six years.
And, you need the printed number on your ballot, which is assigned anonymously.
Unless Trump handed out his ballot numbers, no one can find out whom he voted for, which is what the posted article implies.
