Obama sweeps three states

Barack Obama making a speech.
Barack Obama has won three more states in the battle for the Democratic Party's presidential nomination, BBC online reported.

The Illinois senator won by wide margins in the states of Washington, Louisiana and Nebraska. Obama is neck-and-neck with Hillary Clinton in the nationwide battle to be the party's nominee.
For the Republicans, Mike Huckabee has won the Kansas caucus - although analysts say he still stands no chance of catching front-runner John McCain.
Obama also won caucuses in the US Virgin Islands, according to the online.
The BBC's James Coomarasamy says the results in the Democratic contests will not be decisive, but they will return the momentum to Mr Obama.
As for the Republicans, our correspondent says that Mr Huckabee's victory in Kansas shows that there is a constituency within the Republican Party that is very suspicious of John McCain, and that Mr McCain has some work to do to unite the party.
Mr Huckabee and third-placed Ron Paul have already been coming under pressure to step aside for the sake of party unity, BBC reported
For his part, Mr Huckabee said on Saturday that he had no intention of quitting. "Am I quitting? Let's get that settled right now. No, I'm not. I majored in miracles, and I still believe in them."
Going into Saturday's contests, Mr McCain had a wide lead with 719 delegates, to Mr Huckabee's 198 and Mr Paul's 14.
Mr Romney's suspended campaign still has 298 delegates.
On the Democratic side, Mr Obama and Mrs Clinton are facing the prospect of a long drawn-out battle after neither was able to deliver a knock-out blow in Super Tuesday's 22 state contests.
In advance of the 9 February contests Mrs Clinton had won 1,055 delegates to Mr Obama's 998 of the 2,025 needed to secure victory at the Democratic party convention in August.
Mr Obama's success in Washington, Louisiana and Nebraska will add to his delegate tally and buoy up his supporters.
