Will Kamala's b!tchy personality hurt or help Biden campaign?

Maybe. She started off with a hostile tone and contentious attitude, and then the constant smirking and other exaggerated facial expressions were very off putting. I don't have much confidence that she has the ability or even willingness to be a uniter of a polarized nation. 

Fortunately, your opinion does not reflect reality whatsoever. Harris was personable, empassioned, actually HUMAN whereas Ponce came off like a talking robot. He was such a stiff, he attracted flies. And do you even know the definition of "rude?" Bcuz Pence was the one constantly interrupting both Kamala AND the moderator! He bulldozed them both & talked over his alloted time so often, he almost threw off the network's schedule. The man showed total disregard for the rules and was blatantly manipulative. THAT is "rude" behavior, Sparky.

A woman dared to speak out to a MAN!!!  

The best part of Pence's debate performance was the appearance of the fly that distracted from all his Trump Talking Points. 

This woman is so deceitful. Her voice could summon the Devil.  

That is the narrative the GOP is trying to spin after Pence was so rude to a woman. 

Go ahead, call her "uppity"
