"The Old Man Factor"
I think the fact that John McCain is very old and very much looks his age is probably going to be a problem for him in electoral terms. Still, there’s a question in my mind of why one could raise this issue in a reasonable way. Chuck Norris seems a bit crude here:
I didn’t pick John to support because I’m just afraid that the vice president would wind up taking over his job in that four-year presidency.
Naturally enough, Mike Huckabee just wound up needing to distance himself from those sentiments. The issue here is probably that Norris is too closely identified with Huckabee at this point. You want the issue raised by by people who aren’t just seen as part of your campaign.
