The press release from the Rocky Mountain poll makes it sound like very good news for Terry Goddard:

Phoenix, Arizona. October 11, 2010. Incumbent Jan Brewer holds a three point lead over challenger Democrat Terry Goddard in the Arizona governor’s race and over a fifth of voters remain undecided (21%). Among those voters most likely to go participate in the election, Jan Brewer has a larger lead in the poll (eleven points) and fewer are uncommited (15%). The Libertarian candidate Barry Hess and Green Party candidate Larry Gist are far behind with just six percent of the vote between the two. The Green candidate Larry Gist may be pulling as much as five percent of the vote away from Goddard.

Keep reading, however, and you can see that among likely voters Brewer leads 46 percent to 35 percent. But even that is a big change from the twenty-point leads she routinely polled in August and September.
