Gun control is supported by the GOP base? WTF?
You'd be surprised. It depends heavily on which question you ask. Often questions about specific policies get way more support than more abstract questions. Here's an example from a Quinnipiac national poll from a few days ago (N=1610, MoE = +/-2.4%). For the question:
Do you support or oppose stricter gun laws in the United States?
26% of Republicans answered "support", while 69% answered "oppose". But that same poll also asked:
Do you support or oppose requiring background checks for all gun buyers?
For this question, "support" won 90%-9% among Republicans. The poll also asked:
As you may know, individuals on the U.S. government's terrorist watch list are not allowed to fly on planes. Would you support or oppose banning those on the U.S. government's terrorist watch list from purchasing guns?
which was supported 85%-12% by Republicans. Other polls show similar results. These are both measures that have been debated since the Orlando shootings. PollingReport is a good site for finding polls if you want to see more results for yourself.
You can see this sort of behavior in other issues as well. Health care reform was a big one -- the individual provisions were popular, but when asked about "Obamacare" people gave very negative opinions.
I don't consider theists to be anti-science. Evolution and God are not mutually exclusive.
Of course not. Polls on evolution are careful to distinguish between evolution being "guided by God" and evolution as a purely natural process for that reason. But there does seem to be a floor of about 30% for support for Creationism no matter how the questions are asked. More specific polls are rare, but there's a 2005 Harris poll with some dismaying results (N=1000, MoE=+/-3%).
Do you think human beings developed from earlier species or not?
Did not 54%
Do you believe all plants and animals have evolved from other species or not?
Have not 45%
Do you believe apes and man have a common ancestry or not?
Do not 47%
This seems to have had a priming effect on the standard question:
Which of the following do you believe about how human beings came to be? Human beings evolved from earlier species. Human beings were created directly by God. Human beings are so complex that they required a powerful force or intelligent being to help create them.
Evolved from earlier species 22%
Created directly by God 64%
Powerful force/intelligent being 10%
And finally, the most relevant question for this discussion:
Regardless of what you may personally believe, which of these do you believe should be taught in public schools?
Evolution only. [READ IF NECESSARY: Evolution says that human beings evolved from earlier stages of animals.]
Creationism only. [READ IF NECESSARY: Creationism says that human beings were created directly by God.]
Intelligent design only. [READ IF NECESSARY: Intelligent design says that human beings are so complex that they required a powerful force or intelligent being to help create them.]
Evolution only 12%
Creationism only 23%
Intelligent design only 4%
All three 55%
I don't think there are necessarily a ton of people who are hard-core anti-science ideologues, but the people who are functionally anti-science (in cases that make them uncomfortable) are not a tiny minority by any stretch.
