Would be much more accurate to say "many Americans cringe."
I suspect we're right now close to the classic thirdsies divide.
1/3 cringe, 1/3 are more or less unconcerned, 1/3 still think he is great and are thrilled when he speaks.
The title Un-American American President fits that description too. The first word is a perfect match to the druggie in our White House, the second word is an exact opposite, and the third word is applied by some people mainly because Obama more or less goes through the motions of some actions associated with the formerly distinguished title for which our community organizer is both unqualified and ineligible.
