I expect the actual results to be Sanders +8 and Trump + 9 in the end
If Trump and Cruz are tied and undecideds always break against Trump when push comes to shove, why do you think he'll win by 9 points? Not to mention, Walker hasn't even begun campaigning for Cruz yet.
No offense to Walker, but governors backing a candidate in this cycle hasn't exactly ended well for that candidate in a number of the primaries. Almost so much so where the endorsements are meaningless. (see Hailey in SC, LePage in ME, etc).
