What's Wrong with the Senate

Ezra Klein puts up a letter from the LBJ library regarding the passage of Medicare as a way of showing the unprecedented nature of the filibuster today.

I read the letter before he added his commentary though and assumed that the "what's wrong with the Senate" referred to the fact that out of just the couple Senators named it included two Kennedy's, Al Gore's dad, and Evan Bayh's dad, and he was making a point about the fact that the Senate is (has always been maybe, I don't know?) the most important old boys club in America and frankly most don't give two craps about the vast majority of Americans so long as they get 52% of the vote every six years.
