Does it matter what he thinks about (fill in the blank)? He’s not a legislator, an agency appointee, a judge ... just a mouthpiece.
Exactly. He made it clear multiple times during his press conference that he supports and will be advocating the Presidents Agenda to the public.
Of course it matters what he thinks — how can he convincingly defend policies in which he doesn’t really believe?
You might be right. The Clintons are like that. They are professionally trained to sell anything regardless of their personal beliefs. Personally I don't like this approach of having someone out there selling things they don't believe in. It's phony. But that may be where we are and it might work for all I know.
