What supporters of U.S. political outsider Bernie Sanders will do could be crucial for deciding who wins the White House race in 2016, experts said.
Though Sanders still refused to quit the nomination race after his rival Hillary Clinton has sealed the victory, the public's attention has already shifted to what his supporters will do next or whom they are going to vote for in the 2016 presidential race.
Clinton is eager to woo Sanders supporters, most of them are millennials who are fed up with politicians in Washington. They are also burdened by high student loans and are struggling to make ends meet seven years after the 2008 economic nose dive.
Some experts believe the Sanders crowd may well determine the outcome of the 2016 race to the White house.
"Although Bernie's name will not be on the ballot in November, his supporters could very well decide this election," Republican Strategist Ford O'Connell told Xinhua.
A large number of Sanders supporters are willing to back Clinton after Sanders finally quits the campaign, a recent poll found. But up to 20 percent of Sanders supporters said they are going to support Trump.
"The fact is that some (Sanders supporters) agree with Trump when it comes to trade and corporate donations in politics," O'Connell said.
That's why Trump in recent weeks seems to be echoing Sanders, lambasting the political system as rigged, as Sanders often does, experts noted.
"He's trying to get as many of Bernie's supporters as possible," O'Connell said.
