In Pennsylvania we all have the same election officials we have had for the last 3 years, and I will expect exactly the same procedure I have had at every election since living here, in which I've voted in every election in which I was eligible.
I don't need ID because the election officials know me personally. But the procedure in PA doesn't require ID anyway.
If you vote in PA and are not subject to any additional requirements, you will know tw is just being paranoid. Paranoia will prevent people from voting which is why this particular tactic may backfire on the Ds. They were instructed to make a fuss pre-election. Bad idea.
Have a nice day.
