Roger Hedgecock, disgraced ex-mayor of San Diego and current right wing talk show host, announced on his Feb. 19 program that the "scientific explanation for the lower info voter" is "we continue to support and allow to procreate people who are...clearly not the best" and his ideas about the decline of humanity started "in 2008."
Citing an article in a scientific journal by Stanford geneticist Gerald Crabtree, Hedgecock presented his own interpretation of the article like this: "Now his theory has to do with genetic mutations and the application, now get this, haven't I said this 10,000 times on this program?--the application of Darwinian theory to the liberal welfare state. If we continue to support and allow to procreate people who are, you know, fill in the blank, and clearly not the best, then you are going to wind up with an average dumber and dumber population over time."
For the record, Crabtree's article (dismissed here) mentions nothing about any "liberal welfare state." Hedgecock might have been reading related texts from the right wing chat-website "Free Republic". Hedgecock ends his rant by saying that previously he thought that "we've been on an arc going up. Since 2008 I'm not as sure."
During this same hour of his program when he mentioned a "dumber and dumber population," Hedgecock
-incorrectly suggested that Obama lost every state that had voter ID laws (a viral email conspiracy theory),
-read an article about an Obama-loving short-sale scam artist that also originated as a viral email debunked by Snopes.com in September of 2012, and
-read from a "handwritten note" he had received to assert that Homeland Security was stockpiling assault weapons to prepare for a revolution "to control the people."
