The link below is to a fun little widget that purports to tell you how likely someone with traits you select is to vote Dem or Rep. Turns out that 'people like me' have about a 90% chance of voting Democratic. The last three democrats (only three!) I voted for were extremely conservative Georgia Senator Zell Miller in... uh... 2000 maybe, I think a bog-standard democratic operative in Kansas that I had a personal connection to in 1996 (or maybe '94?), and Bill Clinton in '92.
Fun result: If I switch from 'white' (which I am) to 'black', the chances of voting Democrat drop around 8%. So a black person who has my other characteristics is more likely to favor the Republican party than a white person who does. Weird.
