For telling his listeners to vote for Hillary in the primaries in order to drag out the democratic process. That did two things: 1. Made Obama a sharper candidate ready fora general election and 2. swelled the apparent number of 'hillary voters' which played into McCain's choice to puick a woman as his VP. If Limbaugh hadn't pushed for his listeners to vote Hillary, Texas and Indiana could have gone to Obama in the primaries, Obama would have it wrapped up and been a less strong candidate and this whole PUMA/hillary voter thing would have never gotten the legs it did, and McCain would have picked Pawlenty or Jindal. McCain would have won.
