(USA TODAY) -- Ah, the challenges of hearing President Obama call your dad liar. Makes you want to punch the guy, right?
Tagg Romney, the eldest son of the GOP presidential nominee, joked on a North Carolina radio station that he wanted to jump out of his seat at Tuesday's debate and "take a swing" at Obama as the president repeatedly called out Mitt Romney.
"But you know you can't do that because ... there's a lot of Secret Service between you and him, but also because this is the nature of the process," Romney told Bill LuMaye of WPTF-AM. "They're going to do everything they can do to try to make my dad into someone he's not. We signed up for it. We've gotta kinda sit there and take our punches and then send them right back the other way."
Tagg, 42 years old and a partner in a private-equity company, and the four other "Romney Boys" all do their part for dad on the campaign trail.
