GREEN BAY, Wis. (WFRV)-- While Mitt Romney campaigns in Israel on foreign policy issues, in Wisconsin republican leaders traveled the state on his behalf.

The bus tour kicked off in Green Bay late Sunday morning, with RNC Chairman Reince Priebus, Senator Ron Johnson, Rep. Reid Ribble, and Rep. Tom Petri.

The tours message, "We did build it", is the Romney campaign's response to a remark President Obama made a couple weeks ago on a campaign stop.

The president said this in  Roanoke, Va., on July 13:

"If you were successful, somebody along the line gave you some help. There was a great teacher somewhere in your life. Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges. If you've got a business - you didn't build that. Somebody else made that happen. The Internet didn't get invented on its own. Government research created the Internet so that all the companies could make money off the Internet."

What the Romney campaign is using in ad's and on the trail is this part of the speech, "If you've got a business - you didn't build that. Somebody else made that happen."

President Obama says the quote was taken out of context and was not an attack on small business owners.

The Romney campaign calls it an insult to all business owners.

"Those entrepreneurs that President Obama claims didn't build that business themselves, somebody else built it for them, I believe Americans will reject that philosophy," said Senator Johnson, while on the Romney Bus.  

RNC Reince Priebus said winning Wisconsin will be key to getting Romney to the White House. Priebus said the RNC plans on dedicating a lot of time and money into Wisconsin,  they just bought $60,000 dollars worth of air time in the state.

"If we win Wisconsin its lights out for Barack Obama, it's just that simple, it's 10 electoral votes, we know that Indiana, North Carolina, Virginia, Ohio and Florida get us to 266, so if we win Wisconsin its over and it's a Mitt Romney presidency," said Priebus.

President Obama took Wisconsin in 2008, but, in 2010 republicans swept the state, and in June, Governor Scott Walker survived the recall, it's that momentum Republicans are counting on to continue into the fall.

"I don't know why anyone would expect a different result from November 2010 or the recall,  what has really changed other than our fiscal situation has gotten worse," said Johnson, who was elected in 2010.  

At the Brown County Democratic headquarters, head of the state democratic party, Mike Tate, rejected the "We Built it" bus tour, calling it an attack on the President.

"What we are doing is telling the truth and I think what you're going to continue to see is mistruths and attacks from governor Romney and his spokespeople," said Tate.

Tate said their grass roots efforts in Wisconsin are as strong as ever, and that volunteers are working hard across the state to help get President Obama re-elected.

"We don't need to do these flashy bus tours to try and rally the faithful to support Mitt Romney, democrats in Wisconsin are four square behind the president and they are working hard to make sure people know his record of accomplishment for the people of Wisconsin."

The Romney bus tour went on to Waukesha, where they picked up Rep. Paul Ryan, then on to Janesville.

It continues Monday with stops in Appleton and Germantown with Oklahoma Senator Mike Lee, Congressman Jim Sensenbrenner, and State Senator Alberta Darling.
