Perception is reality, you know? I didn't like the way the Carville slammed her, but I will agree on this... one of my issues with Kamala as a candidate was that she wasn't always verbally fluent in unscripted situations. That isn't to say she isn't smart, because she is. But she has a weakness in off-the-cuff communication skills and she knows it, so once the campaign got going she relied heavily on stock phrases ("turn the page," etc) that started sounding canned and trite after you heard it the third time. Which imo led to the perception that she wasn't very capable or confident. Add in the right-wing smear campaign on her laugh and her IQ and you're not winning over a lot of voters. Then she didn't really have time or frankly the inclination to get in front of people (ie Rogan) to dispel the myths. They were able to frame *her* as the unserious candidate with no platform other than a continuation of Biden's unpopular policies. And frankly her campaign didn't do a great job of communicating about new policies, and instead relied on Trump as a fascist boogeyman... when most Americans couldn't even begin to define the word fascism.
