At the risk of sounding like one of the chronic Democrat pessimists, one of my few fears has been that, considering Trump won an electoral vote majority with under 46% of the vote last time, simply putting his campaign apparatus in the hands of non sycophantic morons could give him a Fighting Chance. The good news here though is that list of people now in charge, especially Jared Kushner, is effing laughable. Moreover, it's almost surely not going to change between now and November As Trump for all 70 some years of his life refuses to listen to experts or anyone outside of his immediate circle. They're all Crooks and pimps and grifters and thus incompetants.
It doesn't sound like anyone that Trump would move into the position after Parscale would be any better equipped than Parscale tbh
