From Keith Olbermann (by way of a
TPM writer):
That not only in that McCain ad were there two underdressed blondes mixed with the black guy in the ad, but there are also images of the Leaning Tower of Pisa, the Washington Monument, and the Victory Column in Berlin, as Bob Herbert put it, "phallic symbols"—three phallic symbols, two blondes and Barack Obama.

Interested in phallic symbols, Keith? I got yer phallic symbol right here -- and it's just for
you.
Seriously, you know that Olbermann is smart enough not to take this nonsense seriously. Apparently, the Obama camp believes that they can get away with the same crap in the general election that they pulled in the primary: Throw opponents off their game by crying "Racism!" at every opportunity. If someone you don't like says "Pass the salt," scream about the racism inherent in the choice of salt.
The trick may work with guilt-addled Dems, but in the general, it'll just piss everyone off.
By the way, a reader asks an interesting question: Is the McCain ad sexist? Using Paris Hilton as a symbol of vapidity amounts to a blond joke. On the other hand, the folks who put the ad together needed a face that instantly conveyed the message "celebrity silliness." I can't think of a male celebrity who would do that job.
Well, maybe Keith Olbermann.
