Exit polls show sharp divide among Democrats

Election officials in Pennsylvania's largest cities reported solid but not record-breaking turnout for the state's Democratic primary after a bruising seven-week campaign.
Hillary Clinton led Barack Obama in published polls going into the primary, the biggest remaining contest of the Democratic presidential race. Analysts had said Obama would need to rack up a wide margin with strong turnout in Philadelphia and its surrounding counties to pull ahead.
CNN projected a Clinton victory. With about a quarter of precincts reporting Tuesday night, she was leading Barack Obama 54-46 percent.
Exit polls indicated that Philadelphia and its suburbs made up more than 30 percent of the vote, and those boxes were tilted heavily toward Obama. But Clinton supporters turned out heavily in Pittsburgh and the counties of western Pennsylvania, and she was racking up similarly lopsided margins in the state's industrial northeast, those surveys found.
