Simplified, Joe needs to announce everything Joe has done thus far is Republicans fault.
Fortunately Joe doesn't know who he is or what he is doing. Joe is running a Bart Simpson Presidency. Joe went into hiding, so you didn't see what he did, you can't prove a thing. Enough for the average fool to believe every word Joe has spoken/done. Remember anything Joe does/did (even dementia, regardless of severity)is better than anything Trump has done.
