Washington state Senate candidate Dino Rossi (R) sounded pleased with his first week on the campaign trail.

"In just the first week, we have signed up over 2,500 people online, attracted over 20,000 Facebook followers, [the] third most of any U.S. Senate candidate and nearly twice that of Senator Murray, and raised over $600,000, including nearly $200,000 online," Rossi said in a statement Thursday. "We did this without an office, phones, or staff. It happened because the people of our great state share my concerns."

Rossi needs to overcome Paul Akers, Don Benton, Clint Didier, Skip Mercer, Sean Salazar and Craig Williams to claim the GOP nod to face Sen. Patty Murray (D-Wash.).

The primary vote is Aug. 17.
