From Bob Schieffer of CBS News:
This is just another sign of the incivility and really the vulgarity of modern American campaigns. These campaigns have gotten so ugly and so nasty, that they’re now tarnishing the whole system…
The thing that has always made our system so strong is that whatever we have thought of the office holders, we have held the offices themselves in high respect. We have respected the office.
I’ve watched a lot of presidents over the years but I can never recall a president stepping off Air Force One, which is itself a symbol of the presidency and American democracy, and being subject to such rudeness.
I think really we’re a better people than this little incident illustrates.
