Firstly, I hope this is the correct place to ask. I am sure that Worldbuilding SE would accept it, and maybe CrossValidated SE, or even Mathematics SE

Driving to work this morning, I heard about the upset in the French primaries, and the announcer stated that “the French say that they do not vote for someone, but, rather, against someone”.

Of course, I am aware of tactical voting, but what if we took that literally?

If each person had a choice of voting +1 for a candidate, or -1 against another, would there be any significant change in outcome? Would things drift towards the centre, for instance, or is it a zero sum game?

Would there be marked difference in effect on different systems of voting, such as winner takes all and proportional representation?

I am sure that it would have ramifications which I cannot foresee, so thought that I would ask here.

What would be the effetc of allowing voting against aparticular candidate?
