Speaking to reporters from President Obama's campaign plane, spokeswoman Jen Psaki said the close race in Wisconsin was inevitable.
Asked if in hindsight the president should have spent more time in the toss-up state, Psaki said no.
“We always knew this state would be harder than it was for us in 2008," she said. "We've had an organization on the ground there since 2008 and we think that continues to be helpful and is one of the reasons we’re going to win Wisconsin on Tuesday. We certainly don’t look back and have any regrets."
She noted that Mitt Romney's running mate, Rep. Paul Ryan, is a "native son" and has visited Wisconsin often (nine times, according to our campaign tracker). She added that Romney is "pouring money there." Obama has spent more than Romney in Wisconsin, but the Republican has been bolstered by outside groups.
Update: Republicans point out that as of May 2012, Obama campaign manager Jim Messina consistently put Wisconsin in the president's column. All of his paths to 270 included Wisconsin.
"After winning the state by 14 points in 2008, President Obama's campaign has been taking Wisconsin for granted all year," said Republican National Committee spokeswoman Kirsten Kukowski. "Now Obama is on defense as Wisconsinites realize Obama left them worse off over the past four years and Mitt Romney rises in the polls."
