I expect the market to remain where it is until the election, barring a massive second wave that forces another round of lockdowns. Even a small second wave will not result in another lockdown, no one has the stomach for that anymore after the first round of lockdowns resulted in over 40 million unemployed in a matter of a month.
If there is no massive second wave and round of new lockdowns, the market will maintain a glide path until November. Then God knows what will happen. Jerome "The Money Printer" Powell will keep printing until then at least, but after that if the money printer goes silent because either Biden is elected or Trump is re-elected then all bets are off. I don't expect the money printer will last through the election. I don't even know if Jerome "Print Fast Print Furious" Powell will start turning it off before the election but I'm sure his boss will try not to let him so we'll see.
Technically he has no boss save a federal judge in a successful lawsuit, though presidents try to jaw bone Fed chairs. In the present case with the same weapon Samson used. But for now, they are aligned, as you note.
