The Democrats have a healthy fundraising, and ground game building. Biden is getting the best people into the right places, and it is going well. Democrats will have somewhere between an above average ground game, and an amazing ground game. Republicans will have somewhere between a below average ground came, and a complete disaster ground game.
To understand where we are already, look at Michigan. Democrats are flush with money, which you would expect at this point. They have opened campaign offices in every county, and are getting staff ready. Meanwhile Republicans have nothing and no one. They claimed to the FEC to have $146,931 on hand, but their accounts are in the negative, and the FEC is trying to figure out if they are lying.
Republicans say they plan to make up for their lack of a ground game by having heavily funded super PACs, but super PACs lack local knowledge. They tend to feel like outsiders with money... because they are outsiders with money.
Maybe Russian propaganda will close the gap, but they seem even more like outsiders.
