Republicans in the Northeast has virtually vanished from high elected office, and many of those that succeed in getting elected do so because they are RINOs, Republicans in name only.
What about Colorado Republicans?
According to a blog of the Public Policy Polling firm, "43% of Colorado Republicans think Barack Obama was not born in the United States, 33% think he was, and 24% are unsure."
WeatherDem at Square State thinks the Republicans polled are simply being contrarian and dishonest in their answers.
I'm not convinced that this is true. The Colorado results are actually more conspiracy ridden than the national average response for Republicans in a Research 2000 poll, but Republicans, and Southerners, show similar trends. See Virginia and North Carolina.
Do you believe that Barack Obama was born in the United States of America?
---- Yes No Not sure
Dem 93 4 3
Rep 42 28 30
Ind 83 8 9
A continuing series of Research 2000 polls sponsored by Daily Kos (most recently this one) have revealed the same pattern, that Republicans and the South are deeply out of touch with basic indisputable facts, on a wide variety of issues.
Indeed, unlike WeatherDem, I think that realizing that there is a large minority of the population that has crazy ideas is a pivotal idea to making a lot of American politics make sense.
