Clinton wins Pennsylvania primary

Hillary Clinton will win the Pennsylvania primary election over Barack Obama, according to projections.

Political analysts said Clinton needed a decisive win in Pennsylvania if she wants to dent Obama's lead in pledged delegates and advance argument for support among uncommitted superdelegates, CNN reported.

HARRISBURG, Pa., -- Democratic presidential hopeful Hillary Clinton beat back rival Barack Obama in the pivotal primary election in Pennsylvania, according to projections.

In projecting Clinton the winner, NBC reported Tuesday that with 21 percent of precincts reporting, Clinton led Obama 53 percent to 47 percent. CNN also gave the New York senator the victory over her colleague from Illinois.

The network reported that African-American voters in the Keystone State supported Obama 92 percent, compared to 8 percent for Clinton, according to exit polls.

Meanwhile, Clinton was widely supported by older voters, with 61 percent of those 65 years or older backing her.

Political analysts said Clinton needed a decisive win in Pennsylvania if she wants to dent Obama's lead in pledged delegates and advance argument for support among uncommitted superdelegates, CNN reported.

Neither candidate is likely to garner the necessary 2,025 pledged delegates to win the nomination before the party's convention in August and must rely on superdeletates -- elected officials and party leaders -- to claim the nomination.
