Women in Iowa narrowly favored Obama, but 47 percent of women here voted for Clinton, versus 34 percent for Obama, according to exit polls. Clinton was also the favorite of registered Democrats, older voters, and residents of working-class enclaves like Manchester, the state's largest city. With fewer young voters in the mix and Senator McCain siphoning off independents, Obama was unable to sustain the momentum of his surprise win in Iowa.
McCain's victory revives his campaign. But with limited money and stiff challenges in other states, it does little to clarify the race for the Republican nomination.
A record 500,000 people – about 62 percent of registered voters – were estimated to have turned out at the polls on an unseasonably warm January day. For voters in both parties, the economy and the war in Iraq were top issues, according to exit polls.
