Proof, at last

The New York Times back in 2004 hit on a key difference between Republicans and Democrats, and it's on a very basic psychological level. You have to scroll through this a bit, but towards the end you come across this little nugget:

Researchers at the University of California, Los Angeles recently looked at how Democrats and Republicans differ in their neural responses to campaign commercials showing images of the Sept. 11 terrorist attacks. Democrats, they found, were more fearful.

Mr. Ruskin of Commercial Alert points to such studies as proof that they pose a threat to society.

"They" being the studies, but you could just as easily say he is talking about Democrats.
