The reaction to Dubai seemed to me to be more public than partisan, when the story hit.
In a miasma of secrets held by the administration, and with a compliant press, the Dubai incident almost seemed to be crystal clear, seemd to be one of clarity, relatively speaking. Here was one incident that we seemed to understand--duh, don't put Middle Easterners in charge of things directly supporting our home security. It seemed to leap out of the gears, with the immediate attention-getting of a leak, though it was just routine, as far as the administration was concerned. The actual reaction of the White House seemed one of being numbed and surprised.
Most Americans' knowledge of the Middle East is meager and marked by sterotypical metaphor.
There has always been a secretive quality regarding the oil and the deals we have with them. I doubt one American in half a million knew anything of the Bush family dealings with the Saudis until Michael Moore put it in a documentary.
All that devisive talk, all those references to "with us or against us," those images of Arabs at airports being shuttled off into side rooms on the news, etc. Partly because of this cumulative inculcation regarding "us and them," we reacted in kind, much like we should have.
I think the administration was caught between their dire, propagandistic messaging and their real back room dealings, much like how Osama Bin Ladin was pimped as the second-coming of Satan, only to have that story peter off into nothing, capped by when Bush causually remarked to a reporter one day that he wasn't much interested in Osama, that he was old (and unimportant) news.
Dubai in charge of our security, at least, was a stellar moment of an easily grasped news story, and gave Americans a chance to offer an opinion about something concrete, and was so welcome that it flew over the heads of even those anally politically correct about matters racial.
