Election Day in America

When it all started 22 months ago, the big issue was the war in Iraq. When the presidential candidates finally gave way to the voters, it was all about the economy. Today, voters began lining up before the polls opened on the eastern seaboard, and the pattern repeated itself with long lines forming across the country. The race, gender and age of the candidates will make this election historic whichever side wins, and the turnout's expected to set a record. Both parties and the Department of Justice are looking for evidence of fraud or disenfranchisement. Is the electorate changing? Do American voters expect more than any president can deliver?  When will we know the results?
