The most politically damaging responses came from an unwitting trio of GOP septuagenarians:
Several GOP senators ruled themselves out because of their age, including 74-year-old Chuck Grassley (Iowa), 76-year-old Pete Domenici (N.M.) and Thad Cochran (Miss.), who is 70. If elected, McCain would be 72 on Inauguration Day.
'I'm too old to be vice president,' Grassley said.
For the record, Dick Cheney is 67.
