From a political point of view he hasn't really done his boss any favors. They sort of assured him and he assured the country that it would be pretty much over last summer. But now not only are we on triple vaxxed (and people who are complied are still getting sick), but we also have school/sport shut downs around the country, still masking (only now they are trying to put kids into N95s), still have shortages, still have inflation, still have hospital problems, have testing shortages (after 2 years!) and more people than ever are getting it (after having been worked up into a fear frenzy about wanting to avoid the virus). So you have all this po'd people who did what they were supposed to and still got sick AND are still being punished for it. They tried to throw the unvaxxed under the bus for that, but when even the triple vaxxed are getting sick, that's a hard sell except to all but the hardest of COVID diehards.
The reality is there wasn't much Biden could have done (other than controlled his party on schools....the white house still hasn't denounced the Chicago Teacher's Union despite being asked the question a few times now) and history would have played out the same way. But the messaging has boxed Biden in. They sold the public zero COVID when from day 1 they should have just said it wasn't going away. Yayaya....you can say how could they have known about Delta and Omicron....some of us here knew and called it down to the regions involved.
Ironically, Biden is going to get hoisted on his own petard for embracing vaccines developed under the Trump admin and trying to claim the credit. He would have been better off politically if he had called it a massive failure of the Trump vax. Someone is going to get tarred for this....the situation politically requires a scapegoat....time to open the betting pools on Biden, Walensky or Fauci (my money is the CDC director gets pilloried...Fauci is way too savvy having survived too many strengths and Biden's handlers won't let it be him).
