See this Harris Interactive poll taken a week or so ago in which 67% of Republicans and 40% of Independents believe President Obama is a Socialist. Roughly the same percentages believe he "wants to take away Americans' right to own guns."
In addition, a majority of Republicans believe he is a Muslim, wants to turn over our sovereignty to a world government, and has done many things that are unconstitutional. Close to 30% of Independents believe these things too.
The large numbers of Independents who believe ill of the President is probably the most important finding here. There are several other findings you may want to check out.
