Trump will get 50% or more in NY, and 60% is not out of the question.
But if he gets less than 50% in any congressional district, the delegate are divided between the top two vote getters in the district.
NYS is a closed primary. Registration I believe is already closed.
Cruz will get many traditional Rush/Levin type of conservative Republicans. Kasich will get the GOPe types. Trump won't get to 60%, it will be close to 50%.
