I think it was back in 08 Limbaugh coordinated operation chaos. In states like Ohio the attempt was to deny Hillary the nomination and Obama would be the weaker candidate. That strategy worked well.
It was the opposite. Rush wanted people to vote for Hillary because he knew Obama was getting traction fast.
I voted for her in Ohio for the same reasons Rush espoused before he even started talking about. I even called it Operation Chaos in my head before I heard him talk about it.
