I would guess that the gender gap would be more pronounced the higher up the economic tree you get.
Over here Labour has always won more male votes than female votes, partly due to the(reasonably accurate) sterotype of a Labour supporter as being white, working class and Northern. The stuff about doping whippits and eating chips with everything is not.
The reason men used to be more inclined to Labour than women is because of the heavily unionised male workforce. In the 1960's most men belonged to a trade union, whereas working women did not. Many British men engaged in heavy industry held strong socialist, populist beliefs whereas women were much more conservative.
In Britain today however it's more of an age voting gap. The average age of Tories in the UK is about 173!
All younger age groups tend to be inclined away from the Tories to LD or Labour. Funny you should say that NASCAR dads are GOP voting and classical music sorts Dem Voting. In Britain it would be the opposite. Beer guzzling, sports obsessed British rednecks are overwhelmingly Labour. The type of person who listens to classical music and dines out in fine restaurants or tea shops is the archetypal Tory.
