Charlie Cook notes that "when Democrats lost their House and Senate majorities in 1994, polling for organized labor showed that the top issue for union members voting Republican for Congress was guns, something that had nothing to do with unions... It was the presidential loss in 2000, on top of the congressional losses in 1994, that convinced the Democratic Party to simply shut up on guns."
"Republicans need to think about this in terms of their emphasis on certain social and cultural issues. The GOP has turned away a large number of highly educated, economically upscale voters who would be a natural fit for the party were it not for these divisive subjects... Generationally, Republicans are killing themselves with voters who are now under 35, who see the party as narrow and intolerant. As Will Rogers used to say, 'When you find yourself in a hole, stop digging.'"
