The bottom line: Civil servants are permitted by law to have personal political opinions, and, with due respect, the calls by Hewitt and others for a special counsel appear detached from reality.
Same old double standard. Right-wingers are allowed to express their opinions, or even to encourage voters (as with Kellyanne Conway's actions) but others may not express opinions that are contrary to the right wing.
Look at Ken Starr, who avowed a hatred of Bill Clinton, as special prosecutor.
Look at Jeff Sessions, an admitted white supremacist, in charge of the DOJ.
