The question is not whether you or me or him thinks he's too old to run; the question is does the media think he's too old? Because they (the media) most certainly want him to run again, so he can lose again, so 0 gets another 4 years.
McCain was the only top tier candidate of either party who couldn't win at least 50% of the 2008 primary vote in his/her home state. The MSM may be setting the table for McCain to run as an independent if he gets knocked off in the primary. No matter what the MSM does, they won't be able to convince the GOP to nominate McCain again at age 76 in 2012 after losing to Obama by 9 million votes.
