Duffy's lawyer has made a strategic mistake. Public blackmail doesn't work. If his aim was to keep Mike Duffy out of a trial (or whatever), he has now guaranteed it.
What is the PMO supposed to do with that? "Oh sorry, didn't mean it."
It would signal to everybody there is something to hide, even if there isn't. That can't stand. The only acceptable response now is to punish Senator Duffy as severely as possible. Abolish the entire Senate if you have to. In fact, please do that.
