Well, I guess that assumption about who a person would vote for if they have to ask how to vote would be a democrat.
Not that that was the situation for your wife, just saying, :-).
As a former poll worker, and precinct chief in Virginia, I was always very sensitive to voters who had questions about machine operation. If I had to tell them where to press to register a vote, I’d always gesture in a way which didn’t favor a particular candidate. This guy should get the maximum penalty.
