Majority? Expressivity? Strategy?

I'm not up really on where this is coming from, but that would be a pretty
challenging pre-election poll by any assumed election method.

No election method can guarantee a majority winner if voters refuse to offer
compromises, whether we're talking rated (approval), ranked (irv/condorcet),
or weighted (cumulative, Borda) election methods. IRV counts majority with
exhausted ballots excluded which isn't quite fair.

A centrist candidate certainly has an advantage in such a 3-way election, no
matter what method. He would claim left/right choices are extreme and he is
the safe vote. No one but a centrist has much hope of getting a majority in
such an election.

Personally, if this is approval voting, and I liked two overall, I'd support
both, knowing the centrist will likely win. If I really only liked one, I
might just bullet vote for that one.
