I don't buy it
A commentator was claiming that most legislators dislike the publicity-seeking camera hogs. Supposedly there are plenty of backbenchers who hate to see McCain, Graham, Schumer and Pelosi making news and wasting time and soiling the reputation of non-hogs.
Sorry, I don't buy it.
In other fields there are good reasons why the sane workers keep quiet, mainly because it wouldn't make any fucking difference. A sane scientist in engineering or agronomy or materials knows that "journalists" won't listen to sanity. A sane scientist working in industry
can't speak at all because he's working under strict NDAs to protect competitive advantage.
Those limitations aren't present in legislatures. Sane legislators, if they exist, have a UNIQUE source of power.
Quorum.
A quorum strike could halt all action until the camera hogs stop wasting time with endless "investigations" of Benghazi or Flynn or RUSSIANMEDDLING.
Quorum strikes don't happen, therefore sane legislators don't exist.
