I changed the title because the real story, which is what the internals of the poll say, is not highlighted in the title. RCP and other sites post these polls with no comment. The poll needs to be examined to see whether its bottom line is accurate and, if not, why not.
Rudy maintains his lead by including voters who do not care and are not paying attention, and who will probably not vote, so it becomes a name recognition contest. Among voters who are paying attention, which is soon to become most of the likely voters, FDT has a clear lead.
