Where's the info for that? I didn't know it existed.
Ill try and track down the report on it. Although they count straight ticket as if you voted for the same party in both President and Congress positions.
Edit:
Actually that was easier to find than I thought. Although this is from Nov 10th so some of the numbers might have changed?
