A note to Americans from Tagg Romney: you can’t punch the president because the Secret Service will get you. Mitt’s eldest son said on a radio interview in North Carolina on Wednesday that he didn’t like the way President Obama called his dad a “liar” at the town-hall debate. Tagg’s reaction: “Jump out of your seat and you want to rush down to the stage and take a swing at him. But you know you can't do that because, well, first because there's a lot of Secret Service between you and him, but also because that's the nature of the process." Tagg’s right, it’s all about democracy or something.
