Trump is well positioned to take PA, NY, NJ OH, MI and WI. In the primaries and in the General.
As far as I can tell out here in CA, he would take the June '16 Primary. Probably all of the Mountain West.
He will not do near as well in the south and Northwest.
But that's all guessing on my part.
The country has been hungry for a message like his for a long time. I know he will win over many Democrat blue collar voters as Reagan. The black vote will be harder to get since they vote 90% Democrat but I think there are many blacks who are getting tired of the old formula that gave them Furgeson and Baltimore. Since the sixties Democrats have fed the Black community a steady diet of welfare and anger and after fifty years what has it gotten them.
Throw Cruz in there and he takes Texas and some other southern states..possibly Florida as well with his hispanic cuban roots...
