As the hypocrite-in-chief takes the moral high ground and vetoes his first bill, Tony Snow, the White House press secretary, rushes to his defense, stating the president will not trade one innocent life to save another.

Hence the phrase "snow job".
If the republicans were looking for somebody who really looked like he had no clue for the press they made a brilliant choice in regards to Mr. Snow.
