What momentum for Cruz?
Here is what Cruz promises his supporters.
He guarantees that he will not win the delegate game on the first ballot.
He guarantees he has no idea whether he will win the 2nd, 3rd or 4th ballots.
That is what the Cruz momentum promises.
I expect none significant, but it is possible that the press will spin his win in Nebraska as a big win, as he will likely get more delegates that day then Trump.
According to my wife, who was listening to the talks show folks, they were pumping Cruz all day.
A lot depends on Indiana. If Trump wins big we may see Nebraska change, but I doubt it.
In any case the real point was even assuming the lower end of the poll results, every thing breaks against him, Trump still ends up with 1253 delegates.
If events break for him, starting with a 44 to 51 delegate win in Indiana, he ends up with around 1329.
