The important thing about this is that it shows that the democrats (as we have surmised) are concerned more with trashing the president than with national security.
And fortuitously, any time they try to initiate an independent investigation, we will be able to wave that memo in their faces.
It is an excellent development.
"1) Pull the majority along as far as we can on issues that may lead to major new disclosures
(snip)
B) Once we identify solid leads the majority does not want to pursue, we would attract more coverage and have greater credibility in that context than one in which we simply launch an independent investigation based on principled but vague notions regarding the use of intelligence."
Translation: The democrat members of the Senate intelligence committee will coerce the Republican members into going along with them on as many 'inconsistencies' as possible. However, they will care less about the issues over which the Republicans cooperate than the items that the Republicans want to downplay. Once the Dems know which issues the Republican members will not readily pursue, those are the items they will pounce on.
BTW, they are using a criminal interrogation technique to ferret out the really "juicy" items.
