Looks like Rush’s followers know how to do as they’re told. CNN:

How big of an impact did Rush Limbaugh’s ‘Operation Chaos’ have in Indiana? Did GOP voters really cross over to create havoc in the Democratic primary by voting for Hillary Clinton, as he’d asked his listeners to do?

Roughly one in ten of the state’s Democratic primary voters were Republican — and that group did vote for Hillary Clinton, 53 to 47 percent over Barack Obama. But hold on: registered Democrats, who made up two-thirds of Tuesday’s primary voters, gave roughly the same edge to Clinton, 53 to 45 percent. Only Independents — who made up about a quarter of the electorate — voted for Obama, 53 to 47 percent.

For whatever reason, self-identified conservative voters did overwhelmingly support Clinton – two out of three cast their votes for the New York senator.
