Sen. Hillary Clinton won Indiana by a mere two points. But it looks like Rush Limbaugh was responsible for all of that margin, and then some:

It’s possible that Operation Chaos may have had an effect: 5.4% of the 1.27 million voters in Indiana's primary were registered Republicans who voted for Clinton, and 60% of those told exit pollers that they would vote for McCain over Clinton (by contrast, most Obama Republicans say they would vote for him over Mac). Assuming that 60% were Limbaugh's minions, that's 41,000 votes for Clinton—in a contest where she won by only 18,000.
