Senator Claire McCaskill: McCain is old and cancerous.

Politics: Seriously, this is the new line of get tough attacks by Obama? Seriously?

On This Week with George Stephanopoulos this morning, Sen. Claire McCaskill, D-Mo., a surrogate for the campaign of Sen. Barack Obama, D-Ill., raised the age and health of Sen. John McCain, R-Ariz., when discussing the qualifications, or lack thereof, of Alaska Gov. Sarah Palin. McCaskill said she stood by her remarks that she's "uncomfortable with anyone, regardless of gender, that is going to be vice president to one of the oldest presidents we've ever had that has never met a world leader." When Stephanopoulos asked her it was fair to raise McCain's age, McCaskill doubled-down and mentioned his past skin cancer, saying, "I think what we're talking about is a reality. Other people talk about his melanoma. We're talking about a reality here that we have to face. This is someone who's going to be one heartbeat away from the presidency. All of us know it. I just think that it's the facts, George, and that's something that we need to start focusing on, are the facts, instead of distortions and lies."
