No, one day voting, polls open at 6 am in NY, close at 6 am the following morning, polls open at 9 am in LA, close at 9 am the following morning. In other words, the polls open and close at the same time throughout the country.
I see your point and I do agree with the concept...except the New York vote won’t change the Ca vote in any way. I do blieve states in the same time zone should have consistent times and days.
