Can you imagine the political (and probably legal) blow-back if the first thing out of the gate Sessions did was to go after Hillary and Obama's senior people? If that had happened, and if Trump and Sessions had appeared to be working in concert on that, then the whole thing would have appeared to be a political vendetta and would have blown up in their faces.
Sessions is now earning a reputation as being independent from Trump and not playing politics. The swamp creatures are lining up to endorse him because they're hoping he'll not do things that Trump wants him to do.
This impression will make it much easier for Sessions to move forward on nailing some of these very powerful people when the time's right.
It would be interesting, if you are correct.
I’m hoping that is the game. Meanwhile, the feds have done a lot of investigating (and everybody thinks that’s a good thing because “they’re gonna get Trump”) and perhaps in a short while we will all learn that these investigations have “raised questions” about Hillary and Obama’s senior people.
I’m not getting my hopes up, but this is at least a possibility.
