EDIT: Orin Kerr speculated about Lichtblau's story:
I would guess that this leak coming from “current and former officials” is an authorized leak designed to see if revealing some information will take the pressure off to reveal more. If I’m right, we’ll see if it works, or if this leak only creates more pressure to release the opinions or at least reveal more about them.

Saying things like this only serves to validate the action. They are elected to serve the people, if they choose to be a terrible person and throw millions of people under the bus for personal gain, then lets call them on it. Call them a terrible person, don't let them off the hook with "they might lose their job".
Senators (and others) enjoy comfortable lives insulated from the consequences of their actions, especially after having retired from politics.
Politics in America may have descended to the point of "suicide elections" where they -- those who seek to subvert democracy to further their own means and ends -- use everything in their power to maximize public support for a particular candidate. The candidate knows that their political career will have been destroyed in the process, however they're promised protection, great wealth, and influence. This process, from recruitment to "execution," requires a great deal of planning but the reward greatly outweighs the risk.
