I think counting mail-in votes starting when the polls open on election day is reasonable... what I think is unreasonable is that there's only one election day. So, I don't know that I agree with you that it should start two weeks early but I can't think of any reason not to start at least one day early so that we have an accurate count when the polls close on Nov. 8.

I'd really like to see some additional early voting options, at least in the larger cities, a few days before election day... options other than mail-in which I just don't personally trust. But regardless, I don't see any reason not to start counting the day before and not releasing any results until polls close on election day.
