In this Boston Globe article, Robert Kuttner argues that the U.S. is not really divided between red states and blue states:

"[O]nly a small minority of Americans are cultural warriors. Mercifully, most Americans hold appropriately complex views on contentious political or moral topics that demand complex thinking. These include the Iraq war, abortion, gay rights, religion, health care, the environment, and other issues that supposedly divide America into warring camps."
