Well, it's election day, the day when - for a brief moment - people really, really care about what happens in Ohio. Soon, the election will be over and that state will be a distant memory, sort of like Seattle after grunge, Australia after Crocodile Dundee or George W. Bush on January 20th, 2009.
Despite what some people say, the two parties are definitely quite different. The Democrats aren't liberal enough for some of you, and the Republicans aren't conservative enough to cheer for the deaths of the poor and uninsured [cough], but issues like the environment, women's health, regulation of small business, net neutrality, copyright, LGBT civil rights, free trade and education are all going to be substantive issues for the next four years.
