The way Trump has been acting in foreign affairs, I seriously doubt Biden can be worse. At least Biden will be the usual US warmonger/out of touch. Trump uses foreign affairs just to run his own hotel businesses or get lobby backing.
The comparison is between a senile figurehead (Biden) and a self-serving cretin (Trump).
Now, maybe if the Corona hadn't happened, Usians would still choose Trump, but thankfully this is very unlikely now.
If I would bet on it yes
but
The "not sure" voters are more than 20% and increasing the last weeks
