Lifetime Of Experience

LIFETIME OF EXPERIENCE....In the "fair time" category, I'll concede that this really is fratricidal in a way that's not excusable:

In a live CNN interview just now, Sen. Clinton repeated, twice, the "Sen. McCain has a lifetime of experience, I have a lifetime of experience, Sen. Obama has one speech in 2002" line. By what logic, exactly, does a member of the Democratic party include the "Sen. McCain has a lifetime of experience" part of that sentence?
