There are a lot of people out there who have been so riled up by the Republican party and conservative media by wild allegations about president Obama and the state of the nation that they have become positively unhinged and now believe the craziest things.
I try not to post the ranting of crazy people but this woman in South Carolina at a Rick Santorum event is emblematic of the kind of people who will attend the political events of the Republican candidates and pose problems for them in answering. The candidates will likely feel that they cannot right out say that what the speaker is saying is nonsense because of fears of alienating other crazies who think like her, but at the same time they have to be mindful that to actually support these allegations would be a disaster for their expectations of being taken seriously by the national media and invite ridicule.
Observe how Santorum tries to thread that needle. He does not repudiate any of her wild allegations but takes one claim (that Obama plans to establish a dictatorship) to segue into Obama’s use of executive orders (that he does in order to counter Republican obstructionism) to imply dictatorial tendencies, and hence implicitly endorse the charge that he is a tyrant.
Expect to see many more of these encounters in the coming election meetings.
