Biden should take the fight to Trump and rhetorically pummel him with his horrific record on COVID, including embarrassing moments like when he suggested injecting disinfectants. If he gets Trump flustered enough, Trump will say something dumb that can be used against him in attack ads. “It is what it is”.
Agreed with your general idea.
Lowering expectations for Biden is the dumbest thing the RNC could've done. Make everyone think Joe Biden has dementia, and then when it's obvious he doesn't... he looks even better by comparison.
Like when the Carter campaign hyped Reagan up as a terrifying extremist, which Reagan nullified just by being warm, optimistic, and friendly.
