I've watched over an hour so far. Very disappointed in the level of discourse. Rand Paul was right that some of that stuff belonged in middle school. I think the primary reason is Trump has dumbed down the entire process. All this talk about name-calling, attacking people's appearance, attacking people's spouses, his stupid facial expressions, etc. is absurd. Huge distraction from the issues. I will lose all faith in my fellow Americans if that man survives this process.
In terms of performance on the merits, I liked Fiorina, Cruz, Rubio, Carson, and Fat Man. Not impressed by Bush. I like Walker, but he was pretty much ignored.
Rand Paul and Huckabee need to quit. So does Trump, but no way does that narcissist quit until his poll numbers tank and/or he starts losing primaries/caucuses.
