The Daily Kos has an interesting post up, with results from a survey of 2,000 self-identified Republicans in the United States.
Many of the statistics are depressing. Only 42% of those surveyed are confident that Barack Obama was born in the US. 24% think he “wants the terrorists to win.” 53% think Sarah Palin is more qualified to be president. There is plenty more homophobia, anti-science sentiment, and so forth.
Unfortunately, there don’t seem to have been any questions about climate change, or the environment in general. The results certainly suggest that conspiracy theories play a significant role in US public opinion.
