In that editorial the actual quote they cite from Chamber has a different tone to it :
“Our No. 1 focus is to make sure, when it comes to the Senate, that we have no loser candidates,” said U.S. Chamber of Commerce top political strategist Scott Reed. “That will be our mantra: No fools on our ticket.”
Gun Grabber Scott Reed’s client list had many fools. Bob Dole and John McCain among many.
That assumes that Cornyn is not a fool, and if they means someone who knows the voice of his master, then I guess he isnt.
