What constitutes typical moderates, weather they are Republicans, Independents, or Democrats (if they even exist anymore lulz) do not really care for excess emotional theatrics. Biden played this appeal to helicopter soccer moms, dindus, and liberal college graduates. The left has lost the blue-collar voters, who have benefited from Trump. Many labor union members will vote Trump in the midwest, even if their union is corrupted enough to endorse Biden, it won't change their individuals votes.
The demographic the dems has targeted is not who matters most in swing states. People aren't going to forget that it was the dems who encouraged rioting and looting in cities. Watch for a spike in Trump votes in urban areas and black voters, even if it isn't enough to feasibly shift the county they are in. It's going to be a process, but pretty soon the Dems are going to pay in collapse due to lack of appeal. The Dems have rejected reform of their platform multiple times already, and the large amount of candidates in the Democrat primary being yes-men only shows that, when somehow Biden won the nomination. People haven't forgotten the stimulus checks Trump authorized or the draconian restrictions Dems mandated at the local and state levels.
