Flake and his Arizona colleage John McCain are not conservatives, and Arizona has done the nation no favors by sending these two to Capitol Hill. But Flake is hardly alone in this - he’s one member of the GOP weak-sister brigade and by himself he could not block Kavanaugh’s confirmation. But he also has Susan Collins and Lisa Murkowski backing his position, making their demand for an FBI investigation unavoidable.
The FBI will find nothing. Clarence Thomas had this happen to him and it was cleared up in two days. The lesson for the enemy is this “be careful what you wish for” because it can come back and bite you in the a$$.
