You state it as fact.
Can you document it?
Start with the resolution to block Trump from when a Rino was supposed to be the Nominee - then look at the published names, many have their office positions but do a little digging and you see prescient captains, big donors etc.
If Cruz had such an awesome ground game and delegate wrangling skills prior to the GOPe taking over his campaign under NeverTrump, why did he do so badly in the south?
What makes more sense? The GOP state machines are helping him under their NeverTrump agenda or he magically got better right after the Bush camp was invited in? Please note how smug the RNC is that they have control over who gets nominated at a contested convention. That’s not the behavior of a pro-Cruz delegate slate.
