While U.S. Democratic presidential candidate Hillary Clinton is still leading the race to her party's nomination, the difficulty she's been having with rival Senator Bernie Sanders underscores a disenfranchised and angry electorate.
Sanders racked up surprise wins Saturday in the states of Washington, Hawaii and Alaska, riding the wave of anti-establishment feeling that is prevalent not only in the Republican Party but among Democrats as well.
Indeed, while much has been made in the media of Republican Party front-runner Donald Trump's high negative ratings, Clinton's negative ratings are nearly as high.
Just last week, a CBS poll showed that the two candidates have the highest unfavorable ratings since 1984, when CBS began asking the question.
Republican strategist Ford O'Connell said there is a sense of disenfranchisement on both sides of the isle. While brash real estate billionaire Donald Trump leads the Republican Party on his anti-establishment message, Sanders' popularity also stems from a sense of disillusionment with Washington elites.
"A lot of what is going on on the right is also going on on the left," O'Connell told Xinhua. "A good number of Democrats are not thrilled with establishment politics either. It's why a protest candidate like Sanders keeps hanging around."
