On a different tack, it always seems that the Dems are able to staff the non-political positions of GAO, security, etc with Dems.
But even when the GOP is in the majority, the Dems still staff everything. I go back to Reagan days when my Congressman, Dan Rostenkowski, of the House Ways and Means committee controlled when and where civil service exams were given and who could get past his goons to take the exam for Dept of the Treasury, HHS, IRS, Social Security, etc.
Bing Bing Bing, now that may be the real motive and the place to start looking. Who could have pulled it off.
When a republican president takes over the political appointees change but the civil service underlings stay on and leak info, sabotage efforts, etc. to reduce the effectiveness of the appointee and there is nothing that can be done. It is a major weakness in the government.
