Republican Presidential front-runner candidate Mitt Romney is expected to make a campaign stop again in Delaware County Monday – a day before the Pennsylvania primary election. “I think the Romney campaign knows the importance of Delaware County for the general election (in November),” said Delaware County Republican Party Chairman Andrew Reilly. Romney, a former Massachusetts governor, will be hosting a town hall meeting at Mustang Expediting in Chester Township. He is expected to be joined by U.S. Sen. Marco Rubio, R-Fla. Reilly said that the Delaware County GOP proposed several sites to the Romney campaign for this event, which is slated to begin at 12:30 p.m. “We were pleased to help them locate a site,” Reilly said. Romney made his first campaign stop in Pennsylvania at the Iron Shop in Marple earlier this month. “We’re happy that he’s coming to Delaware County again,” said Reilly. Romney is facing Texas Congressman Ron Paul and former House Speaker Newt Gingrich in the primary. Former Pennsylvania U.S. Sen. Rick Santorum suspended his campaign earlier this month. Reilly said anyone interested in attending the Romney town hall Monday should RSVP by sending an email to TeamPA@MittRomney.com.
