John Bolton passes through the revolving door Mark Leon Goldberg July 29, 2009 Here in Washington, the term "revolving door" refers to the phenomenon of former government officials taking up private sector posititions to lobby their former colleagues for lucrative government contracts. This is very common and afflicts both parties with equal opportunity. Indeed, even the most committed and die-hard ideologues are not immune from the pressure to cash out and draw on the contacts they have made in years of government service. For instance, one John R. Bolton has joined the board of EMS Technologies, a firm that describes itself as "a leading provider of wireless connectivity solutions over satellite and terrestrial networks." In a release earlier this month, EMS touted a new effort to boost government sales.
