Robert Mueller was supposed to be above reproach, a consummate professional, the one man whose integrity was unimpeachable.  In other words, he–and his handpicked pack of Hillary tongue bathers/donors–was going to get Trump.  But there was no getting to be gotten.  As I’ve repeatedly noted, there can be no obstruction of justice if there is no justice–no underlying crime–to obstruct.  Then there is the small matter of Trump’s near-complete cooperation with Mueller’s investigation.  All he denied Mueller was the opportunity to walk into a perjury trap.
