Quite possibly. I think some of his outrage has been in the works for years. Carville was solidly in the tank for Hillary, having managed one of Bubba's campaigns and wanting to see Hillary- not Trump- win obviously. He is extremely outspoken but he also keeps a lid on it when it comes to faults that come close to Camp Clinton. And he trashes the DNC only because the clintons and some of the other usual suspects are not there anymore. But Carville is a smart cookie, and he also lives in Louisiana, a state that has plenty of deplorables and black people as well. No way in hell- with his savvy-ness- that he did not see that Hillary's focus on transgender bathrooms, illegals-First, anti-walmart-types messaging, was a prescription for disaster or misguided at best. He knows that Bernie's campaign platofrm is just another leg-out from the last totally out-of-touch Hillary campaign. It's just that he is a clinton ally and she hates Bernie and so he has approval from Chappaqua- or at least no problems- in going full balls-to-the-walls against Bernie. If he had done that against Hillary at the right place and the right time, she would be in the White House right now.
Looks like Bernie Sanders is gaining momentum. He is up there with Buttigieg and Biden, Warren falling off. With Republican voters helping him in South Carolina, he might even win that state as well. Of course, he is not getting the nomination but, a very bad Democrat Party civil war between the Socialists vs Globalists is about to start in earnest.
It's good if Bernie wins because the establishment with fight harder for Buttigieg. There will be more 'Iowas'.
Bernie has what...23 delegates needed out of 1,991.... let's not put the crown on his head just yet...
