Poll: Democrats lead McCain among singles

PRINCETON, N.J., May 23 (UPI) -- Democratic presidential hopefuls Hillary Clinton and Barack Obama lead Republican John McCain among unmarried voters, a U.S. poll indicates.

McCain, however, beats both Clinton and Obama among married voters, the Gallup Poll Daily tracking found.

Obama leads McCain by 23 points among unmarried women and by 16 points among unmarried men. Clinton bests McCain by 31 points among unmarried women and by six points among unmarried men.

McCain leads Obama by 17 points among married men and holds a 6-point advantage among married women.

The results, based on interviews with more than 18,000 registered voters from Gallup Poll Daily tracking in May, are similar to what Gallup observed in other recent presidential elections.

In the last three presidential elections, the Republican candidate has fared better among married voters of either gender. The Democratic candidate has won among unmarried voters of both genders in all three elections since 1996.

Usually, married men show the greatest support for the Republican candidate, while unmarried women most strongly back the Democratic candidate, Gallup said.

The poll's margin of error is plus or minus 2 percent.
