(CNN) - Republican Senate candidate Dino Rossi is out Tuesday with his first TV commercial in Washington – an intimate, positive ad that seeks to take advantage of the state's unique non-partisan primary system.
"I worked my way through college waxing floors at the Space Needle. That's why I can't stand what's going on in the U.S. Senate," Rossi says in the 30-second spot. "They're wasting money. On programs that aren't creating jobs or helping the economy. And running up debt that's threatening our future. That goes against everything I believe."
The ad doesn't mention the Republican Party or the name of Rossi's biggest obstacle to election, incumbent Democratic Sen. Patty Murray.
The 30-second spot is hitting airwaves statewide just as Murray released a new ad tying Rossi to former President George W. Bush and slamming him for his connections with Wall Street bankers.
"Dino Rossi first refused to take a position on Wall Street reform, then he had a fundraiser on Wall Street and another in Washington with corporate lobbyists," the ad's narrator says. "Next thing you know, Dino sides with his big money friends and calls for the repeal of financial reforms. Dino Rossi – the best friend Wall Street and big banks can buy."
Rossi's campaign says the two ads highlight the difference between the candidates.
"The contrast between Dino Rossi and Patty Murray could not be more clear: on the day Dino launches a positive ad to talk about issues like out of control spending which are important to Washington voters, Patty Murray goes on the attack with a false ad which makes no mention of her 18 year record of growing government, raising taxes, and pushing job-killing legislation," Rossi campaign spokeswoman Jennifer Morris told CNN.
Murray's once clear path to a fourth term has grown increasingly competitive since Rossi announced his candidacy in late May. According to The Elway Poll, in a non-partisan survey a survey conducted June 9-13, Murray led Rossi by a 47-40 point margin in a hypothetical general election match-up. The poll's margin of error is plus/minus 5 points.
Washington's primary will be held on August 17. They are the only non-partisan primaries in the nation; in each race, all candidates are pooled together regardless of party affiliation, and the top two vote-getters advance to the general election.
