SHEBOYGAN, Wis. -

State Sen. Joe Leibham has raised $300,000 for his run for the Wisconsin congressional seat now held by retiring Republican Rep. Tom Petri.

Leibham is one of four Republicans running for the seat. The winner of their Aug. 12 primary will face Democratic Winnebago County Executive Mark Harris in the November general election.

A campaign finance report filed Tuesday also shows Leibham spent about $26,000 and finished the quarter that ended June 30 with about $280,000 in cash on hand.

Leibham has loaned his campaign $10,000 of his own money.

State Rep. Duey Stroebel is personally funding most of his campaign for the Wisconsin congressional seat.

A campaign finance report filed Tuesday shows Stroebel has raised a little more than $26,000 for the 6th District race in east-central Wisconsin. But he has loaned his campaign more than $340,000.

Stroebel has significant real estate and business holdings.

His campaign spent more than $190,000 during the quarter that ended June 30, leaving it with about $177,000 in the bank.

Stroebel faces a four-way Republican primary on Aug. 12 primary. The winner will challenge Democratic Winnebago County Executive Mark Harris in the November general election.
