It's clear we're seeing a pattern of how McCain is flubbing lines, getting confused, and generally out of it often on the trail. Why is it so politically incorrect to say that, as a condition of his age and the demands of the presidency, that he isn't qualified for this job at this time. Every job in the world has physical, mental, and overall health requirements. While one cannot specifically be denied a position because they are "too old" (although most people are eagerly looking to retire and relax at 65 to 70 years old) they surely can be denied b/c they don't have the health level to meet the job demands.
We have a number of successful Senators who are much older than McCain. Why is it so non-PC to say that he should stay in the Senate where his health limitations due to age aren't an issue and conversely that he isn't qualified to be president which is arguably one of the most demanding jobs in the world.
Of course if McCain is elected, inaugurated, and can't serve(even temporarily) Palin is confident that she's ready and qualified to step in because you can see Russia from Alaska.
