Wolcott on why Mitt Romney is likely bummed the whole immigration thing is over:

To exploit the bill’s unpopularity, Romney’s crack team of advisors had planned to strap an illegal alien to the top of Romney’s motorcade limo and chauffeur the undocumented worker around New Hampshire from campaign stop to campaign stop. This publicity brainstorm was intended to serve double duty: highlighting Romney’s opposition to illegal immigration and converting the media storm over his strapping the family dog, an Irish setter named Seamus, to the roof of the car on a long vacation trip until the poor animal diarrhea’d (”‘Dad!…Gross!” A brown liquid was dripping down the back window…”) into a political plus. His staff convinced their doofus boss that his best bet to defuse the controversy was to tackle it head-on on his own terms. To prevent similar bowel troubles from bedevilling the wind-whipped rooftop Guatamalan or Mexican in custody, Romney’s “people” intended to have a Port-o-potty hooked up to one of the motorcade cars and make regular “pit stops” at gas stations where Mitt could have his picture taken at the pumps. With the defeat of the immigration bill, alas, the lease on the Port-o-potty has been null-and-voided and Mitt’s eager-beaver staffers have been pulled off the manhunt for a suitably grungy looking illegal immigrant with no English language skills and sinister eyebrows. If Romney were Fred Thompson or Rudy Giuliani, he could strap an ex-wife to the top of his car, but given that that option is denied him perhaps he and his political team should just forget the whole thing.
