Operation Chaos supported voting for Hillary over Obama, the premise being she was the lesser of two evils, not so much she would be easier to beat.
That’s not true. It was already inevitable Obama was going to be the nominee. Operation Chaos was birthed to make the primary campaign longer and make them both spend money against each other. OC prolonged the primary for several months when otherwise, Obama would have been able to coast and raise money instead of having to campaign and spend.
