(Washington Times) Wisconsin Gov. Scott Walker criticized Mitt Romney’s campaign on Wednesday for being too passive in its response to attacks from the campaign of President Obama.

The Republican governor, considered a rising star in the party, said on MSNBC’s “Morning Joe” that he thinks Mr. Romney has done too little to lay out his own vision for the country and is relying too heavily on public dissatisfaction to sweep the president from office in November.

“I think there’s a lot of caution,” he said. “I think the mistake that they’ve made is this feeling that [the race] can just be a referendum on the president.”
