A day in the lives of presidential candidates Bob Russell, Matt Santos, and Arnold Vinick, who are in Iowa trying to gain support for their campaigns. Iowa is the first state in the nation to hold their presidential caucuses, and issues affecting farmers and rural areas are the focus. The most important issue on the table is the large federal subsidies for ethanol fuel given to corn growers, which is supported by Iowa residents but seen as naked pandering by the rest of the country. Josh continues to clash with Santos over winning votes instead of proposing radical policy. Donna and Josh continue to avoid speaking about the state of their relationship.
