I think what he means is “Trump continues to redefine the rules”. Which is what conservatives have begged for for decades...
Can anyone argue with that statement? We all know damn well it was rigged and sprung on Trump, he didn't like it and is now retaliating. This whole thing was a setup from the get go to be rid of Trump and he is pissed. He is leading the entire pack and does not need to go into another rigged debate. I applaud him for standing his ground. I blame the whole thing on the GOP establishment, Fox News and Megan Kelley but their plan backfired.
