Ideally, maybe, but this depends on the assumption of sincere

But that's a very big assumption. In a public election there's
no chance that many voters would keep voting sincerely when
they realize they can do better if they don't. For instance,
in your example, the B voters, the 51%, would have no incentive
to give A any points, in a point-rating election. B would then
win. Even in a many candidate election, a group consisting of
a majority would be able to get what it wants, and would
strategize in order to do so. The important thing is to
not force people to use strategy in order to get what they're
numerically able to get. e.g. Progressives shouldn't have to
abandon fully voting the progressive over the Democrat in order
to help the Democrat beat the Republican, in case the progressive
can't win, & the progressive + Democrat group constitutes a majority
that can beat the Republican. The lesser-of-2-evils problem.
