An unthinkable campaign ad has me thinking about the unthinkable

Not long ago, the unthinkable — a Scott Brown victory over Martha Coakley — became the distinctly possible and, following the latest gaffe by the Coakley campaign, it may now have ascended to the realm of the “about as likely as not.”
The gaffe occurred when the Coakley campaign and the Democratic Senatorial Campaign Committee decided to attack Brown as the agent of “Wall Street greed.” Not terribly original, but not a bad idea either.
Unfortunately for Coakley, the picture selected by the DSCC to symbolize Wall Street greed shows the World Trade Center. Talk about a negative campaign ad.
Meanwhile, President Obama has decided to head for Massachusetts on Sunday to campaign for Coakley. He apparently believes that the unthinkable has indeed become the “about as likely as not.”
