I estimate that over 99% of the US population is unaffected by these Washington carryings-on and knows something between nothing and very little beyond the condensed conclusions that for more than a year now have been trumpeted to them by the (mostly) coast based media.
There may or may not be something dodgy about Carter Page, or about the Justice Department's request to the FISC for a surveillance warrant on him. That will come out in legal proceedings some time in the future. Release of the Republican memo about it, or the Democratic counter-memo, is unlikely to affect that one way or another; federal judges are not likely to be swayed by such politically motivated nonsense.
On the other hand, the notion that all this is an existential crisis for the US government approaches insanity.
