Well said. You have to know the rules of the game your are playing.
This is quite true. I recall hearing in a first semester undergraduate course in political science 41 years ago, that that central question in politics can be expressed as the question “who decides?” [Thanks, and a tip of the Hatlo hat to Donald K. Emmerson, Emeritus Professor at The University of Wisconsin at Madison.]
In the chase for the nomination, one needs to understand that the delegates decide at the convention. To varying degrees the primary voters select delegates, delegates with varying obligations to be bound through successive ballots. These are dictated by the rules which will stand until the rules committee reports to the convention at large, when the dynamic rules that apply to a convention may, yet again, change.
Those who are wetting the bed over Cruz’s success in garnering delegates under the rules might consider that, if their candidate is on the losing end of delegate selections, perhaps they should stop pounding the table and consider that someone who cannot understand and strategize within the existing rules, might not be the best person to place in the White House, where the challenge is infinitely greater.
And you also have to know which rules aren't really rules, they are merely labeled such.
