What are you talking about?
The Louisiana rules are straight-forward -- the Rubio delegates became unbound when Rubio withdrew from the race.
These delegates were available to Trump, as well. Except his staff apparently didn't know the Louisiana rules as well as the Cruz people.
So, why is this the fault of the "oligarchy"? Why is not the fault of Trump and his campaign staff's?
Maybe the rules, but Cruz has no awesome ground game. GOPe ground game! Bushes & Mitt threw support to Cruz, it became the oligarchys ground game.
Cruz is just a dick.
