Taken within context...
I sure won't object to being called a "grey" -- in fact, I'd be proud to own it.
And I don't think you've made a bad call with any of the other grey Zoners on your short list.
[of course, some of them are grey otherwise, too... me, for one]
As for Presidents, or candidates for the office, a lot of greys have run (or tried to) and didn't make it, either. Bob Dole and John McClain come to mind, right off the top.
