Exactly two weeks after Rick Santorum announced he was dropping out of the race for the GOP nomination for president, Mitt Romney was on track to take more than 50 percent of the vote in Pennsylvania, with a 56% to 19% lead over Santorum with 43 percent of precincts reporting.

Ron Paul was in third place with 14% while Newt Gingrich, whose loss in Delaware fueled speculation that he was ready to drop out, was last among those on the ballot with 11%.

Turnout across the state was said to be low for this primary election without many high-profile, hot-button races.

This primary was the first election contest to implement a controversial law requiring voters to present a valid ID at the polls. Enforcement of the new statute was said to vary.
