Fox's Preliminary Pennsylvania Exit Polls

As of 7 pm ET:

African Americans: Obama 92, Clinton 8

White men: Clinton 55, Obama 45

Made unfair attacks: Clinton 67, Obama 49

Did it hurt Clinton to go negative? More than half of the voters said the ads the candidates run mattered, but most of those voters said they picked Hillary Clinton.

If Clinton isn't the nominee, her supporters in general election would vote for: Obama 50, McCain 26, stay home 19.

If Obama isn't the nominee, her supporters in the general election would vote for: Clinton 67, McCain 17, stay home 12.

Union households: Clinton 58, Obama 42

Lower income voters (under $50,000): Clinton 55, Obama 45

Voters with college degree: Obama 54, Clinton 46

Urban Voters: Obama 69, Clinton 31

Gun owners: Clinton 58, Obama 42

Church goers: Clinton 59, Obama 41

In touch with people like me: Obama 65, Clinton 64

Black voters and young voters are moving toward Obama, but in "older, whiter Pennsylvania," that could make it tough for him "and so far today that's what we are seeing."
