“Both were Rafael Cruz supporters, IIRC.”
ALL delegates APPOINTED by the Colorado GOP establishment criminals were Cruz delegates, which I always found to be an odd choice for the establishment given that Cruz was claiming to be an outsider. And the Colorado “caucuses” were held well BEFORE the choices had been winnowed down to just Trump and Cruz, so there were plenty of other candidates to still choose from.
I thought the Wisconsin support for Cruz was strange too.
