McGrath mentions the politicians supporting the "No" vote claim it will be too difficult for us. My favourite misleading claim is this one: "AV would undermine the principle of one person, one vote, by giving greater weight to choices of those who put fringe parties first and whose second-choice votes could decide results" - a statement that is either mathematically illiterate (ok, pedants, innumerate) or careless in its phrasing. Or both, of course.
