Of course everyone all over the Globe are worried about their pocketbooks including Conservative Government run nations like the UK that has been hit far harder in every respect as compared to both the USA and Canada. The blame always falls at the hands of the Government except to you if it is a right wing Government in power!!
Biden did flip the States that mattered for him to win an overwhelming majority. That is what really matters in giving the Democrats some power. There is some positiveness that maybe taking root:
Historically, the generic ballot has overstated Democratic performance.

Again a lot os assumption from you as to what "types" of Democrats may flip those seats, if they take those States. Does not automatically mean that they will be Manchin or Sinema clones arising from those captures!!
Eventually at least the Democrats managed to pass the most revolutionary bill, such as the Affordable Healthcare Act. Something that the Republicans attacked from the word go and threw several roadblocks during the passage of it.
Anyway, how can the Democrats now nominate any more Supreme Court Judges if none of them are either quitting or dying?
Once again did the Republicans not have the likes of McCain, Murkowski and Collins to do with the likes of the ACA plus several other Bills, that Manchin and Sinema are currently doing to prevent the new Roe v Wade Legislation!! Why do you only aim your criticisms at one party only?
