Hermann-Brown is my choice, mostly because she seems the most professional and least political. I don't like political hacks overseeing elections. This should really be a non-political office.
I think early voting is bad. Sure, if you are ill or will be out of town on election day, then early voting or absentee voting is fine, butthose are the only people who should vote early.
I think most early voting now is driven by top of the ticket, high money races and the political hacks. Early voting hurts the undercard races and candidates who only have enough money to get their message out late in the campaign. Many of these races don't get covered by media until the week before the election.
