Well we know the AZ race with tighten significantly. I believe Clinton won the state by 8 points '08. I wonder if she can do better. Perhaps 10-15 points? She will need a good performance in AZ to pad the likely thrashing she'll get in ID and UT. I'm thinking Bernie nets 15-25 delegates next Tuesday. Surprisingly she almost cracked 40% in UT in '08. A little resources and a campaign stop can make that a 10-point race.
After Michigan/Ohio, I don't know that it will. I'm sure Sanders will outspend her there, but he outspent her in Missouri 4-1. Latinos haven't been his best group, especially near the border.
