It seems that while the Senate Dems go through their kabuki theater, the Republicans aren't really into it.
Some Republican Senators are being criticized for not sitting in rapt attention as Democrats make their case for impeachment. One Republican was seen chewing gum on the floor. Another was nodding off (just like half the viewers).
I haven't watched it today and don't intend to. As a cop, I have sat politely through many hours of arcane legal proceedings, watching attorneys take care of he procedural minutia of the Courts. It's all important work, but not unlike watching paint dry.
Were I a sitting Senator, I'd probably be in my office, doing something productive. I suppose those Senators who are dozing off are giving th proceeding the attention it deserves.
