Our Take:
Since September, the polling has been remarkably stable. Martin O’Malley has received 49% support three times, 48% support once and 47% support once. Bob Ehrlich has received five different levels of support at 38%, 39%, 41%, 43% and 44%. Neither candidate is showing much of a trend in any direction. The mean results are O’Malley at 48.4% and Ehrlich at 41.0%. That is just within the margin of error, which has averaged around four points.
Interestingly, while both candidates enjoy nearly universal name recognition, the Post reports that 48% of its respondents are persuadable. Despite O’Malley’s lead in every poll so far, this is a real race.
