I think what has really helped BIden is the Ukraine situation, in which Zelensky et al are a great advertisement for brave liberal democracy (and it also marginalizes/outs lying/racist/Nationalist Putin-lovers Trump and T Calson). It makes Biden look resolute and strong without committing any troops. Easy call to "stand up to China" also, waiting to see if they/Taiwan become another Russia/Ukraine. Nutty Trump acolytes also making Biden look highly rational as MAGA/QAnon lose steam. Now we have to wait and see if Newsom replaces him on '24 ticket (while dumping Harris). I never thought Biden should veer too far left since he stands to gain many votes from disgusted moderate Republicans
