Blurred lines

Many observers said it is too early to have a clear picture of where the future of the US might lead to.

"Right now, Trump has the support of white, blue collar voters while Sanders has the support of the younger generation. But the traditional line [of the demographic groups] has become blurred so no one can make a good prediction based on past observances," Jin Canrong, vice director of the School of International Studies at the Renmin University of China told the Global Times.

Jin said public opinion has become polarized and fragmented.

The US has been suffering from political polarization as it has become more difficult for members of the two parties to reach consensus and act decisively.

"Both candidates make emotional appeals … Their parties, on the other hand, are not seeking a party realignment," Jin said.

Analysts also said US foreign policy won't avoid being affected by the result of the elections.

"If Trump is elected president, it would indicate a recalibration of US foreign policy toward contracting global interests," Ni said.

Trump previously suggested pulling troops out of Japan and South Korea, which has stirred Washington's two key alliances in East Asia.

However, if Hillary Clinton is elected, she is likely to continue the same foreign policy adopted by the US in the two decades following the end of the Cold War, which is based on ideals of democracy and human rights, analysts said.
