By the normal rules of debate Harris lost. She lied constantly, she engaged in ad hominins constantly, she avoided answering specific questions asked her by the obviously biased moderators.
But by the rules currently in effect she won.
Harris won this debate.
She achieved the goals that she set out to achieve. And she prevented Trump from achieving the goals that he had set out to achieve. She needled him she goaded him she triggered him into responding to her instead of focusing like a laser on her flaws. She knew she couldn't run on her record and so her goal was to prevent Trump from attacking her record.
He should have brushed aside her attempts to distract him instead of responding to them. He should have remained focused like a laser on immigration, crime, inflation, global instability. Furthermore he should have refused to get sucked into any discussion about abortion. He should have stated his position and then pivoted to immigration crime inflation global instability.
