Democratic presidential hopeful Hillary Clinton reacts as she greets supporters at her Super Tuesday primary night rally in New York. Clinton won California, Massachusetts, New Jersey and New York. Despite these big ticket victories, Obama's numerous victories make the day look like a draw.
Barack Obama took Connecticut, Gerogia, Minnesota, Illinois and a number of other states. Here he is seen at his "Super Tuesday" primary election night rally in Chicago.
Obama took 12 states, while Clinton took eight. "Our time has come," Obama told cheering supporters in Chicago. "Our movement is real, and change is coming to America."
Hillary Clinton also adopted the message of change. "Tonight we are hearing the voices of people across America -- people of all ages, of all colors, of all faiths, of all walks of life," Clinton told her supporters at a rally in New York. "Tonight, in record numbers, you voted not just to make history, but to remake America."
Republican contender John McCain won nine states, including key victories in California and big Northeastern states to take a strong lead in the Republican race. "Tonight, I think we must get used to the idea that we are the Republican Party frontrunner for the nomination," McCain told supporters in Scottsdale, Arizona. "And I don't really mind it one bit."
But Republican rivals Mitt Romney and Mike Huckabee kept their hopes alive and vowed to fight on. Romney won six states and Huckabee won five.
A new round of contests in a half-dozen states are scheduled this weekend and in the coming week.
The Clinton and Obama camps said they expected the count of delegates for the night to be relatively even. "We think the delegates are going to be very close and we may end up with an edge there," Obama campaign manager David Plouffe said.
All over the world, people stayed up late or woke up early to follow the results of the election. Here, a man in Japan watches result reports on a Tokyo street.
