White House hopeful Bernie Sanders extended his winning streak in his bid to pull off a shock and defeat Hillary Clinton, grabbing victory in the Wyoming Democratic caucuses, the US media said.
The state -- which is overwhelmingly Republican -- awards only 14 delegates, meaning Sanders barely puts a dent in Clinton's more than 200-delegate lead, but it gives the self-described democratic socialist another morale boost, ahead of the crucial New York primary on April 19.
The Vermont senator won 56 per cent of the Wyoming vote to 44 per cent for Clinton, CNN projected yesterday, with most ballots counted.
Clinton though remains the clear frontrunner for the Democratic party ticket for November's general election, but Sanders has the momentum and has enjoyed a string of successes at the polls.
Speaking to supporters in New York, Sanders broke into his speech to say to cheers: "All right. News bulletin. We just won Wyoming.
Earnest said Obama is eager to join the campaign and make
a case for Clinton before American people.
"The president's very enthusiastic about the opportunity that he will have over the course of the next several months to make a strong case in support of Secretary Clinton," he said.
"I think that is evident from the comments that President Obama made in Elkhart, Indiana last week. The stakes in this election are high, particularly if you look at the US economy," he said.
"We've made enormous progress over the last seven years digging out of the ditch created by the worst economic downturn since the Great Depression.
"The private sector is what led that recovery, but the private sector would not have succeed without the important policy decisions that were made in the first couple of months of President Obama's presidency," he added.
"So, for those voters who are focused on the economy, we have got a pretty strong case to make about the wisdom of the decisions made by President Obama and the commitment by Secretary Clinton to those principles," Earnest said.
