I'm not happy at all...but I understand there's a process. Running for office is a purely voluntary activity. Those who criticize the choices have credibility to the degree they're willing to take the shots themselves.
Following your statement to it's logical conclusion, then 99.99999999999999% of the populace has no credibility when it comes to criticizing any entrant into the race for president as they have not done so themselves. Further, we have no business criticizing any govt activity unless we've been there, done that ourselves, which once again leaves out the vast majority of the populace.
That's the same sort of mentaility the left espouses when any conservative makes a statement in favor of using the military to further our nation's interests. According to the left, if you haven't been in combat you have no business advocating for it.
