Dark green = 80%+ of ballots returned.
Light green = 70-80% of ballots returned.
Yellow = 60-70% of ballots returned.
Red = 50-60% of ballots returned.
Purple = 40-50% of ballots returned.
Once 95%+ of ballots in a county have been returned, the county color will turn blue.
Now for the fun stuff.
1. Dem firewall is now almost at 450,000+.
2. Collar counties are still struggling with their returns. They better hope their slower reporting is straightened out on Election Night or else it's going to be a long week for all of us.
3. Allegheny area remains in good shape. Butler's a little weird, but almost nobody lives there. Pittsburgh itself has a little over 2/3s of theirs in and should cross 70% tomorrow.
