While covering the Iowa caucus, NBC's Nightly News Andrea Mitchell said that the state's influence on the presidential selection process had been lessened due to its lack of diversity.

“The rap on Iowa, it doesn’t represent the rest of the country,” she said. "Too white, too evangelical, too rural. Still here, politics are personal.”

According to a Census 2010 report, over 91 percent of Iowa's population is white. The state kicks off the nation's presidential election season tomorrow with its Republican caucuses.
