Perhaps the most damning poll stat for Trump, who one GOP strategist described to me as a "lifelong predator brand:" Biden's net favorability has *improved* the more the president has intensified his attacks.
It seems clear from Biden's messaging, the DNC, etc that boosting his favorability numbers was a big goal. A lot of "he's a good guy" type stuff. I think it's fair to say that policy has been secondary. I think it's also fair to say the plan has worked.
Tho as reminds me, the debate really did boost Biden's favorability
