Ha! She's as relatable as a rattlesnake!
The point of Carville's rant was that the kids (i.e. 23 year olds) tanked her campaign, simply by providing the leadership she couldn't provide. For example, they shut down her interview with Joe Rogan - HARD.
But the fact is, they were entirely correct. She couldn't answer Joe Rogan's questions for 3 seconds, let alone 3 hours! It would have been more of a disaster than the Joe Biden vs Trump debate. And the 23 year olds KNEW that.
