Mitt Romney's Sons Tried To Convince Him To Not Run For President

Mitt Romney's five sons made a rare joint public appearance on Thursday evening, when they sat down with Conan O'Brien to talk about their father's presidential campaign.

While appearing on TBS' "Conan," the five Romney brothers-- Tagg, Matt, Josh, Ben, and Craig -- weighed in on how their lives may change if their father wins the election.

"We’re nervous about it,” Josh, the middle brother, said. “It’s one of those things. Our lives are pretty good as they are, but this is one of those things where we recognize it’s good for the country for my dad to run but not necessarily good for us, so we are going to try and keep our lives as normal, as consistent as they can possibly be over the next few years.”

Josh said that his father's failed bid for the Republican nomination in 2008 made the family wary of another campaign.

"We knew what we were getting into this time, so we were definitely more hesitant," Josh said.

Matt, the second oldest of the Romney sons, admitted that he had similar reservations about his father's second stab at the presidency.

"I didn't want him to do it," Matt said. "I tried to convince him not to. I think there were a few of us who tried that ... but I just felt like, for us as a family, this isn’t the best thing. But, as Josh said, for the country we think it’s the right thing."

The Romney sons have had a relatively small role in their father's 2012 campaign, largely staying out of the spotlight except for a few election night appearances and fundraising efforts. In 2008, they had a much more prominent role: an RV known as the "Five Brothers Bus" was a regular sight at campaign stops, and the brothers maintained a blog that offered details from life on the trail.
