Literally no. If they were gonna vote Trump instead but decided to go with Harris, their vote is worth the same as someone who would always vote Harris or the vote of a leftist who decided on damage reduction.

Any voting system flattens our personal motivations into a single action. Any statement you're looking to make is moot unless you have a massive campaign to make it clear outside of the ballot box. Even then, the establishment can downplay and misinterpret your motivation as not being representative or as less important than what they want to believe.

There's no better way to translate our will into results. Any system that doesn't use free and fair voting can be tainted and colored by bias, making it impossible to ever undermine the will of the establishment. They will always choose to believe whatever is most convenient, but votes can deliver a reality shock that forces them to adjust their behavior, even if they never change their minds. The only other thing capable of that is violence.
