SurveyUSA reports that Gov. Bob Ehrlich's approval rating is sharply up. Fifty-two percent of Marylanders now approve of Ehrlich compared to only 44% in June. The number who disapprove of Ehrlich is down to 43% from 51% in June. Markedly increased support from women appears to be driving the numbers. Ehrlich's approval ratings among women jumped from 37% in June to 51% in July. The number of women who disapprove of Ehrlich declined from 56% to 43%. Among independents, crucial to Ehrlich's reelection prospects, the Governor's approval rating is up to 57% from 52% and disapproval down to 35% from 42%. However, the margin of error in the poll is much higher for subgroups (+/- 5.9% for women, +/- 10.7% for independents) than for the poll as whole (+/- 4.1%) so take these conclusions with a grain of salt.
