I never said people would dump their favorites in the poll and I can't see
any
rational person doing so (unless they had the kind of omniscience it would
take to predict the effect on other voters). What I was referring to is
voters who
would be likely to vote two (or more) candidates in the election, stating
in a poll that they will only vote for one (their favorite). Thus if I say I
will vote
A and not AB, I might hope to cause some B voters to vote AB as well.
