Here's a post (reached via Marginal Revolution) with some depressing statistics. Turns out non-college Republicans and Democrats are reasonably close on whether global warming exists and is caused by human activity. Or, if not reasonably, the difference is only 21 percentage points. But college educated Reps and Dems differ unreasonably, by 56 percentage points. In other words, the more education you have, the more you differ.
This does grave violence to my remaining goo-goo tendencies. Good government types, perhaps descended from the Progressives and Social Gospelers of 1900, believe in good, solid facts and, with a religious fervor, if one could only lift the cloud of error from people's eyes, everyone would believe the same, meaning there would be peace and love in the valley.
