Back when there was a push to get an IRV initiative on the Oregon ballot I sat in on some of the FairVoteOregon meetings, including the one in which the final wording of the initiative and the wording of the voter information pamphlet entry were being hashed out. All the rhetoric was repetition

It looks like you're trying to set up a straw man, but I think the reasoning is pretty sound. This very thing happened with Dean and Kerry before the nomination was locked up - people that would ideally prefer Dean to Kerry would vote for Kerry, because the herd was going with Kerry. Curt On
