Republicans running for Indiana's two open congressional seats were among the most successful fundraisers in the second quarter of the year, according to disclosure reports filed Friday.

The reports also show that GOP challenger John McGoff outraised Rep. Dan Burton, R-Indianapolis, in the 5th District race, and the two Democrats hoping to unseat freshman Rep. Larry Bucshon, R-Newburgh, in the 8th District are willing to bet their own money on the race.

The most successful fundraiser among the state's House candidates was former state Rep. Jackie Walorski, who raised $229,202 from April through June in the race for the open 2nd District seat. Walorski last year unsuccessfully challenged Democratic Rep. Joe Donnelly, who is running for the Senate.

Walorski is the only Republicanin the north-central Indiana district who has created a fundraising committee. Democratic lawyer Andrew Straw, Goshen, has raised about $4,300, most of it his own money.

Walorski has been tapped by House Republicans for their recruitment and training program, as she was in 2010. Her donors include House Majority Leader Eric Cantor of Virginia, whose political action committee gave Walorski $5,000 last month.
