The Gonzales Research and Marketing Strategies poll found 47 percent support O'Malley and 42 percent favor Ehrlich.
Ehrlich supporters may be inclined to focus on the 5 percentage point gap as smaller than the 8-point one in the last Rasmussen poll or the 11-point lead for O'Malley in a Washington Post poll late last month
But the trend line is bound to be more comforting to stat watchers on the O'Malley side. In July, Gonzales found O'Malley was the choice of 45 percent of likely voters, while 42 percent preferred Ehrlich, and 8 percent were undecided.
Essentially, a quarter of those Gonzales counted as undecided in July now say they will back O'Malley for a second term. Meanwhile, the percentage saying they will back Ehrlich has remained roughly unchanged.
Four percent of voters would choose a third party candidate. Six percent were undecided.
