Obama now leads Democrat race

In the latest set of primary contests, Democrats in Virginia, Maryland and Washington DC emphatically backed Obama, giving him a straight run of wins in the last eight states to vote.
It's a devastating blow to Hillary Clinton's team, who are desperate to halt the growing momentum behind Senator Obama's campaign.
