Camus was not a very optimistic person, and that is an assumption that can be made from his novel the stranger. Judging on his outlook on life, I would say that Camus would probably vote for whoever he feels that the majority is going to vote for, because he'd feel that literally, his one vote, would not change anything. Originally I wanted to say that he would vote for Gary Jonson because unfortunately he has no shot at winning, so in that case it wouldn't really make a difference. I actually can't say with confidence who Voltaire would vote for neither, but I will make a guess and say Jill Stein. I would say Jill Stein because Voltaire is for cultivating your garden and thats something that he has in common with Jill Stein and the Green Party.
