Republicans are more skeptical of the theory of evolution, though by a surprisingly slim margin with 39 percent of them rejecting it as compared to 30 percent of Republicans. When it comes to other scientific matters, the waters are even muddier. For instance, Democrats and Republicans believe in the false link between vaccines and autism at roughly equal levels.

And it’s largely liberal Democratic politicians pushing anti-vaping laws, despite public health agencies estimating e-cigarettes to be around 95% safer than conventional tobacco cigarettes and early evidence they help smokers quit. And vaping products don’t contain any tobacco or its resultant tar, yet the FDA still wants to treat them as tobacco products.

The big science policy issue of the day, though, seems to be global warming. Sixty-four percent of Democrats believe in man-made global warming, while only 22 percent of Republicans do. But when it comes to realistic solutions to reduce greenhouse gas emissions, Democrats still aren’t always science-minded.
