Clinton keeps race alive with win in Pa.

Sen. Hillary Rodham Clinton (N.Y.) has won the Pennsylvania Democratic primary over rival and frontrunner Sen. Barack Obama (Ill.), according to news networks, keeping alive the former first lady’s hopes of becoming her party’s presidential nominee.

{mosads}Clinton, who benefitted from the state’s large blue-collar and rural demographic, held off Obama despite his estimated three-to-one spending advantage in the state's most expensive primary in history.

Most analysts agreed that anything less than a win by Clinton would have doomed her attempt at a comeback in the fight for the nomination.

What is still in question, however, is whether her margin of victory will be enough to further stoke that comeback or continue to cast doubts on her ability to overtake Obama in the popular vote count. Catching Obama in the race for pledged delegates is a near impossibility for Clinton given the number of states that have yet to cast their ballots and the Democratic Party’s system of divvying up delegates proportionally by congressional district.
