(CNN)– The age factor turned out to be a double-edged sword for John McCain, according to partial exit poll results.

McCain counted on attracting older voters and, indeed, did better among the 65-plus age group than among any other - capturing 54 percent of voters age 65 and older compared with 48 percent among 30-to-64 year olds and 30 percent among those under age 30.

However, many older voters expressed concern about the age factor, and among this group Obama beat McCain. In total, 39 percent of 65-and-older voters said age was a factor in their vote; among these voters, 56 percent supported Obama and 44 percent went for McCain.
