From what I have seen, you are correct in your assessment of those folks at these events. Many of those interviewed even say they voted for Obama. They are upset because they didn’t expect what he is trying to do.
Even my wife, an independent, who voted for Obama, thought she was voting for something totally different than what we are getting. My in-laws, a surgeon and nurse both voted for Obama but are also very dismayed over what has been happening and up in arms about the drastic changes proposed to health care.
Various parts of the media are either complicit in helping Obama reshape America as a socialist nation or still in denial over what is happening.
I am very disturbed over what is occurring politically particularly the aspect that our 4th estate, the media , is no longer primarily for news reporting but in their selection of what to cover and how to cover the “new’ are more like propaganda every day.
Most recently, the coverage of Van Jones and Acorn have demonstrated that some parts of the media don’t want the most transparent administration ever. They are more comfortable with folks not knowing what is going on.
