MI-Mitchell/FOX 2 Detroit: Clinton+18

[IceSpear]

A Clinton win of any size in Michigan dooms Sanders' campaign.

Under 10 but mostly within 5 would be great for him!

Sanders is down 197 delegates, any loss for him is terrible. He literally can not afford to loose anywhere.

The reality of the delegate math has yet to sink in. I guess the Bernie people are counting on winning California by 50 points.

A <10% loss for Bernie here wouldn't be "good" for him, but it wouldn't be terrible in that the delegate gap wouldn't dramatically increase. If Sanders can win the West by huge margins, losing some of these states by small margins won't doom him. An 18-point loss is definitely bad for him, though.

It's obviously not about winning the nomination now. It is about winning states/delegates and continuing to push Clinton to the left. He can't win here because of the black vote but maybe he can give her a bit of a scare.

Crappy pollsters (which Michigan have a lot of) tend to have strong swings in small windows of time. There's probably a swing towards Sanders going on but a better pollster would be needed to verify.
