THAT NICE ROMNEY LAD

BILL LUMAYE: I’m going to ask something I think a lot of people want to know, or at least I do. What is it like for you to hear the President of the United States call your dad a liar. How do you react to that? 

TAGG ROMNEY: Jump out of your seat and you want to rush down to the debate stage and take a swing at him. But you know you can’t do that because… Well, first there is a lot of Secret Service between you and him but also because this is the nature of the process.

As Melissa in the comments said:

Huh. I thought violent people weren't supposed to come from two parent households.

Seemingly, respect for the office of President of the United States was not high on the training agenda for the five Romney lads, or perhaps Tagg models his dad.  We all saw during the second debate that Mitt treated President Barack Obama like one of "the help".  Like father, like son?
