Keith Rothfus, GOP candidate for PA-12, received the endorsement of the U.S. Chamber of Commerce Thursday morning. Rothfus’ latest endorsement potentially opens the doors for new donors outside of the state.

The PA Dems ran an online contest for their candidates in PA’s 18 congressional districts. The winner: Missa Eaton, challenging Rep. Mike Kelly. The prize: a fundraising email likely worth a few thousand bucks.

Three PA districts: the 12th, 8th and 6th, were included in a National Journal report listing the 75 House districts expected to be the most highly competitive in the country – meaning those that could experience a shift in partisan control come Election Day.

The conservative super PAC Congressional Leadership Fund is reserving television time in the Philadelphia media market for fall political advertisements, with plans to spend $1.6M.

Q2 figures are in and the congressional race in PA-6 is likely to remain competitive. Jim Gerlach raised a healthy $341K to Manan Trivedi’s $260K, though he has more COH than any other Dem challenger in the state.

Phil Scollo has gained a bit of ground in fundraising against Rep. Tom Marino, but still faces a huge deficit in the GOP-friendly 10th district. The Democratic businessman raked in over $60,000 in the second quarter; Marino pulled in just under $100,000.

Q2 fundraising totals from PA-8 candidates Kathy Boockvar and incumbent Rep. Mike Fitzpatrick weren’t far apart. While Fitzpatrick raised more than his opponent, $395,501 to $329,802, both candidates had an impressive quarter.
