I'm disappointed in this story, which leads for a long time with complaints from the Obama campaign of Limbaugh's influence before getting to what evidence exists, which isn't much. "Her eight-point advantage among Republicans, nearly all of whom are white in the state, was much narrower than it was among white Democrats, whom she won by nearly 2 to 1 over Obama."

This is a very detailed look at whether Rush Limbaugh's "Operation Chaos" may have harmed Barack Obama in the North Carolina and Indiana primaries. Limbaugh had been urging his listeners to vote for Hillary Clinton in order to prolong the Democrats' agony. Though factually solid, the story falls apart by failing to make a critical connection. It may be true, as political scientist Edward Carmines says, that "Operation Chaos" wasn't "a major factor." But Clinton's margin over Obama in Indiana was so small that Limbaugh's shenanigan's may well have been decisive.

I know talk radio's had an effect on election campaigns, but--yikes!

Uses exit poll data without source identification. Fairly considers both sides.

Great bit of journalistic digging. Add up the numbers and it certainly looks like some kind of "sabotage" since Hillary only won by 14000 votes in the end. Even so, it's not clear she would have backed out even if Obama had won by a similarly small margin, so probably not an effective strategy. Still, somewhat disturbing. Upside is that it makes Obama look stronger for Nov. if he did as well as he did even with 10% of the voters being republican.

They should have worked out the math and explained more explicitly that leading by 8 points on 10% of the vote (total vote around 1.26 million) means an extra margin of about 9500 votes, and that Clinton was the winner even without the Republican cross-overs.

I don't believe Rush has much influence. I think people realize he's not fair or balanced (mentally or politically)
