Iowa's brutal winter weather is making an unrepresentative process even less representative. The subzero temperatures, icy roads and life-threatening wind chills may keep some Republican caucusgoers home on Monday.

The state's population is whiter, more rural and evangelical than the rest of the nation. As Iowa has become a firmly Republican state, the two major parties have diverged on their nominating schedules: The Democrats are starting on Feb. 3 with South Carolina while the GOP is sticking with Iowa. But some experts say there's an argument for kicking things off in a small state.
