Per ABC News, Portman “came out swinging” today in Colorado, where he stumped for Mitt Romney and bought a few cinnamon rolls at a diner.

“President Obama has been attacking relentlessly,” Portman said. “In 2008, he said that if you’re out of fresh ideas, use stale tactics against your opponent — you try and make your opponent unacceptable. And that’s what he is trying to do.”
