Hillary Clinton brings her life journey to the Sundance film festival

Hillary Clinton has returned to the political stage at the Sundance film festival with a vow to work to defeat her Republican antagonist Donald Trump in November.

Hillary, a documentary about the former Democratic standard bearer, screened at the prestigious festival ahead of its world premiere.

Due to air in March as a four-part series on streaming site Hulu, it already has made waves in a turbulent election year.

Clinton’s caustic remarks in the documentary about Senator Bernie Sanders, her rival for the Democratic nomination in 2016 and now a frontrunner in the current race, received wide play in the US media.

At the festival, Clinton kept her focus on Trump, whose shock victory a little over three years ago stunned the country and cut short her seemingly unstoppable political ascent.

“I just think we have to win. I don’t think we can afford another four years by the current incumbent,” she told reporters.

“It  would be absolutely dangerous to our democracy, and I’ll do whatever I can to make sure the Democrats win this time,” she said.

Backed by a phalanx of security unusual for such events, the former secretary of state extended her remarks in a clutch of red carpet interviews.

“We have to be better than the other side, because they highly organized and incredibly well funded, and they have foreign help,” she told.

“We should win, because I think people can see the broken promises and the failed actions of this current administration,” Clinton said.

“And so we should win, but we’re gonna have to overcome all of the obstacles they are throwing our way,” she said.
