Keep telling them you’re a Cruz supporter so they’ll make you a delegate, then switch to Trump when you’re unbound :)
“...then switch to Trump when you’re unbound :)”
Actually, I was thinking about that as I was typing it! What is to stop people from doing that? Although at the state convention where it will really matter, the delegates to the national convention will probably be the higher-ups in the party and have to rely on their integrity if they want to be involved in the future.
