At a rally Saturday in Milwaukee, President Obama continued an argument that he began earlier in the week with potential voters in Green Bay: That he was still the candidate of change.
"We know what change is, what the future requires, and Wisconsin, it wont be easy," said President Obama.
"The next phase of change wont be easy, back in 2008, folks swept up in excitement, had posters, but sometimes people didn't hear me when I said change we believe in isn't just changing presidents, changing parties, its changing our politics, changing the system," the president continued.
The message resonated with some in the crowd like independent voter Tim Madler of Wauwatosa.
"I think he gets it, and I don't think a lot of the politicians I've seen over the years do get it," said Madler. "So I think Barack Obama gets it."
Many supporters in the crowd seemed to understand just how close Wisconsin could be on Election Day.
"It's pretty scary," said Sandi Julius of Racine. "I mean, I just pray that we can pull it out. I think we're going to do it, but it's going to be a fight, that's for sure."
The president seemed to agree.
"And if you're willing to work with me and knock on doors with me and make some phone calls with me and grab your friends with me, and grab your neighbors and coworkers and get them to the polls with me," said President Obama, "we'll win Wisconsin. We'll win this election."
At the rally, pop star Katy Perry sported a skin-tight minidress with Obama's campaign slogan "Forward" emblazoned across it.
Perry came on stage at Saturday's event initially wearing a red, white and blue dress and holding a microphone shaped like the Statue of Liberty's torch.
But after her first song, a cover of Al Green's soul hit "Let's Stay Together," she tossed aside the dress to reveal the bright blue minidress.
Obama's slogan "Forward" is also Wisconsin's state motto.
Perry paused midway through her set to make a pitch for donations to victims of Superstorm Sandy.
Obama's rally with Perry came before he's set to be in Madison on Monday with Bruce Springsteen.
