HARRISBURG — U.S. Rep. Allyson Schwartz on Monday became the fourth Democrat to declare her candidacy for Pennsylvania governor in 2014.

“I’m running to replace (Republican Gov.) Tom Corbett. That’s what this race is about,” the fifth-term congresswoman said.

Schwartz, 64, who has said for weeks that she intended to run, filed papers Monday with the Pennsylvania State Department to set up a state fundraising committee.

She also transferred $3.1 million into the new committee, nearly all of it from her congressional campaign committee and the remainder from a state legislative campaign committee, campaign spokesman Reesa Kossoff said.

Schwartz served in the state Senate for 14 years before being elected to Congress. She faces a potentially crowded field in a gubernatorial primary that’s more than a year away.
