Would it be nicer if we lived in a multi party system? Probably. Do we? No. Voting as though we are is not useful (maybe unless you live in a state that you are 100% certain can not be flipped).
If you hate one candidate even slightly less than the other, for example because the former has not yet stated that they want to punish colleges that allow pro Palestine demonstrations, vote for that first one.
Vegetables are a social construct.
