Al Giordano notes of the PR exit polls:

Only five percent of Clinton voters wouldn’t be satisfied with a Clinton nomination. That’s a much lower number than has occurred in other states that voted once Rush Limbaugh began his “Operation Chaos” urging Republican-supporting voters to prank the Democratic primaries by voting for Clinton. Spanish-speaking Puerto Rico, obviously, is a place where Limbaugh has no significant listenership, and this provides us a yardstick with which to measure Limbaugh’s actual impact on English-speaking state primaries.

In Kentucky for example, on May 20, a full 19 percent of Clinton’s voters said they would not be satisfied with her nomination. On May 13, an equal number - 19 percent - of her own voters in West Virginia said they wouldn’t be satisfied with her nomination. But only five percent in Puerto Rico were in that category. This suggests that 14 percent of Clinton’s vote in recent mainland state primaries consisted of the Limbaugh “chaos” voters.

That's giving Limbaigh too much credit, I think. But he did have an impact in some states.
