Cheney's attendance at Senate

(From the diaries, Cheney presided over the Senate a grand total of two times the past four years -- just as many times as Edwards, who also did so twice. Slightly edited -- kos)
"Now, in my capacity as vice president, I am the president of Senate, the presiding officer. I'm up in the Senate most Tuesdays when they're in session."
--Dick Cheney

The extended entry has the presiding officers over the last four years for every Tuesday session.
