The attacks provoked a near lynch mob atmosphere at her rallies, with supporters yelling "terrorist" and "kill him" until the McCain campaign ordered her to tone down the rhetoric.
But it has now emerged that her demagogic tone may have unintentionally encouraged white supremacists to go even further.
The Secret Service warned the Obama family in mid October that they had seen a dramatic increase in the number of threats against the Democratic candidate, coinciding with Mrs Palin’s attacks.
There is no excuse for the hate and racism that was displayed at many Republican campaign events and I would find it hard to believe that Palin did not know what she was doing (although she apparently didn’t know that Africa was a continent so the point is debatable). As crowds at her rallies shouted racial slurs directed at Obama, racist signs and even nooses were displayed on numerous occasions, she did nothing.
Sarah Palin is not the only one to blame. At any point during the election season, someone in the campaign could have said something. For the most part, that did not happen. McCain did seem to have one moment of clarity however. Possibly he realized what he and Palin had created was out of control and arguably responsible for their plummeting poll numbers. It proved to be too little too late.
There is one other phenomena that can be attributed to, or blamed on, Palin’s rhetoric — landslide defeat of the GOP. But I should stop playing the blame game.
