The Fed Emp’s here are scared stiff that Obama will win. They like him, but can't afford to vote for him.
It comes down to there JOBS or the O Messiah!!!!!!!!!
As a retired USAF officer who spent more than his fair share of time in the Metro DC area, I can hazard a guess as to an additional reason. There are very few white career civil service types in the federal government who have not be victimized at least once by seeing their promotion, or new job, go to a less qualified Affirmative Action hire.
And then, as often happens, when that Affirmative Action hire has been promoted too far and too fast and cannot actually perform the job, the rest of the employees have to suck up the extra load and in addition to doing their own job, do the Affirmative Action hire's work too. And when this happens, these employees are absolutely livid, but have to keep quiet about it for fear of losing their jobs. But they absolutely seethe over it. And they seethe for long periods of time.
If my speculation is accurate, my guess would be that a lot of these civil servants have heard, loud and clear, Obama's not-so-coded message that Affirmative Action is going to receive new emphasis in the federal workplace. And they know who will be paying the price. And therefore, they aren't supporting Obama in the numbers one might anticipate.
