The broadening of Obama's appeal for the nomination seen in Gallup's May 16-18 polling is fairly widespread, with the percentage favoring him increasing among most demographic categories of Democratic voters. However, as a result, certain groups that were already highly supportive of Obama for the nomination -- men, 18- to 29-year-olds, postgrads, and upper-income Democrats -- are now overwhelmingly in his camp. Obama is currently favored among these groups by a 2-to-1 margin, or better, over Clinton.

At the same time, support for Clinton among some of her traditionally stalwart support groups -- women, Easterners, whites, adults with no college education, and Hispanics -- has fallen below 50%.

The only major demographic group still supporting Clinton to the tune of 51% or more is women aged 50 and older. This group's preferences have changed little during May, at the same time that Clinton's support among younger men (those 18 to 49) has declined by nearly 10 points.

Bottom Line
After nearly 20 grueling weeks on the campaign trail since he shook up the Democratic primary race by winning the Iowa caucuses, Obama has finally stretched his lead over his chief rival into the teens.
Having previously captured nearly the maximum level of support from black voters, Obama's latest gains have come from a broad spectrum of rank-and-file Democrats. At least for now, he has expanded his position as the preferred candidate of men, young adults, and highly educated Democrats, and has erased Clinton's advantages with most of her prior core constituency groups, including women, the less well-educated, and whites.
