Not to start unnecessary concerns, but Vote-By-Mail shows more votes returned for Republicans than Democrats. Some are touting this as a Trump advantage, but if you drill down, the requests [Rep/Dem] for ballots in 2008 were 51% to 32%. This year it's 43% to 38%, a narrower gap. So historically mail-in ballots are more a Repub thing. This year, more Dems, fewer Repubs. So I suspect advantage Hillary, ultimately. But I'm no expert ... just looking for things that might indicate poll errors (none so far).
