The Senate Commerce Committee has 23 members! It’s easy to snooze at the meetings and not be noticed
I suspect that McCain is hugely over-rated as a Senator.
The source of McCain's influence seems to trace solely to when he put on his bi-partisan hat and went along with the Democrats.
Has he ever sponsored and won legislation which was actually conservative, in any way? Has he ever been involved in any initiatives which were partisan.
McCain is a "successful" Senator only because the Democrats (and the media) have made him so.
It's time for him to go.
