>> When Rush was for it in 2012 <<
Rush’s Operation Chaos? That was in 2008, when he was encouraging conservatives to vote for Obama in the Democratic primaries — with the thought that Obama would be weaker in the general election than Hillary. Great strategy that turned out to be!
Except you got it backwards!
Operation Chaos was designed to get votes for Hillary, so as to equalize the race and create chaos at the Denver convention.
