Between spearheading the cancer-education and fundraising Lance Armstrong Foundation and dating Kate Hudson
, Lance Armstrong has his hands full.
But the cancer survivor and cyclist hinted Thursday night that he may be interested in expanding his empire to include something more: public service.
"There might come a time when you feel like you've reached a wall and you need to step into public office and try to make change through that channel or those ends," Armstrong, 36, told reporters at the Foundation's Livestrong Summit in Columbus, Ohio – which was attended by presumptive Republican Presidential candidate John McCain.
In an interview from the summit with CNN
's Campbell Brown, Armstrong noted that both McCain and Democratic contender Barack Obama support cancer research.
"Both candidates I believe care about this issue," said Armstrong. "Senator McCain is a cancer survivor himself. Senator Obama, I know, is committed after having lost his mother to this disease."
At the summit, McCain told attendees, "Lance Armstrong is making all the difference in the world, and I'm honored to be in his company."
Still, Armstrong remained coy with reporters in one regard – which of the two politicians would make the better exercise partner.
"I don't have an answer for you on who I would workout with," said Armstrong. "Probably best just to do a little triathlon. You know, we could hike one day with Senator McCain and play basketball one day with Senator Obama and then the other day they have to go ride with me, and then we’ll figure it out."
