I don't remember either party doing that. Democrats had no problem blaming Trump for all the Covid misinformation he spread and his failure to encourage the people to follow CDC guidelines but I never heard democrats thanking him for the work he and his administration did to get vaccines available within one year. Likewise, republicans roasted Obama over promises that no one would lose their insurance and would be able to keep their doctor, but never mention the additional millions of people that would have insurance and the expanded benefits for all that Obamacare brought.
I can think of a number things I don't like about Biden but Republican ignored those things and have hung their hat on two issues, inflation and gas prices. That's because everybody hates paying more at the gas pump and at the grocery store. The fact that Biden has no control over either is completely irrelevant. Since most people don't like the president; that is, they voted for him because they thought he wasn't as bad as the other guy, they don't need much convincing that he messed up. It has nothing to do with what the president did or did not do.
What is really strange is a party can convince voters to vote against a candidate that is only guilty of being a member of the president's party. In other words the candidate is guilty by association.
