WASHINGTON — Hillary Rodham Clinton took a serious beating in a poll released Tuesday — with a majority of voters describing her as dishonest and untrustworthy.

The CNN/ORC International poll showed Clinton’s numbers have plunged in almost every category over the past two months as scandals swirled over her email accounts, family foundation and fat speaking fees.

Her worst showing in a poll since 2001 included:

57 percent of voters say she is not honest and trustworthy, up from 49 percent in March.

Just 47 percent feel she cares about people like them, down from 53 percent last July.

And 50 percent now feel she does not inspire confidence, up from 42 percent in March.

Neil Newhouse, a Republican pollster, said the results show the “significant obstacles” Clinton will have to overcome as she campaigns for the White House in the months ahead. “It’s a yellow flag for the Clinton campaign that this is something they have to deal with,” he told The Post.

“The goodwill and diplomatic credentials Clinton built up as secretary of state have eroded since she announced her presidential run and worsened with the drip, drip of bad news for the candidate. It poses a challenge for her,” added Newhouse, Mitt Romney’s former pollster.

“These concerns that voters have about being trustworthy — that’s something that’s she’s going to have to address. And that’s a difficult attribute to demonstrate. Rehab work is needed.”

But GOP operative and commentator Tara Setmayer wrote on CNN, “Ultimately, no matter how hard Hillary’s campaign tries to control media access and messaging, it’s difficult to reshape opinion about the likeability factor of someone who’s been in the public eye for 25 years. Given the multitude of platforms by which information can be dispersed to the masses, it becomes a Herculean task.”

The question of whether the former first lady and secretary of state is honest has dogged Hillary for years. But the latest poll follows the publication of Peter ­Schweizer’s “Clinton Cash,” a damning exposé of the Clinton Foundation’s questionable dealings with foreign governments during her stint at State as well as how she and hubby Bill have cashed in on speaking fees at home and abroad.

And the numbers are sinking despite Clinton’s fresh campaign message on championing the middle class.

“Clinton has had a difficult few months — avoiding the press doesn’t spare you from the effects of bad news and scandal,” said Larry Sabato, director of the Center for Politics at the University of Virginia. Still, he said, the numbers are bound to change between now and November 2016.

Clinton will seek to turn the tide with her first big public campaign rally, on Roosevelt Island on June 13, which is expected to draw a big homecoming crowd.

Since Clinton launched her second bid for the White House in April, she’s favored small campaign stops with handpicked guests in early voting states and has limited questions from the press.

Along the way, she’s outlined liberal campaign platforms — expanding President Obama’s immigration orders if Congress fails to pass reforms, raising the minimum wage and passing equal pay legislation, ending mass incarceration and supporting gay marriage nationwide.

The intimate settings were billed as a chance for Clinton to listen to concerns of everyday Americans, but polling shows she hasn’t come off as empathetic. Less than half of voters say Clinton cares about people like them (47 percent, compared to 53 percent in July) and 50 percent feel Clinton does not inspire confidence, the CNN/ORC poll found.

And while she still leads the field of GOP challengers, the margins are slipping fast and are now tighter than they have been at any point in CNN/ORC’s polling on the 2016 presidential contest.

Clinton is about even with Kentucky Sen. Rand Paul, Wisconsin Gov. Scott Walker and Florida Sen. Marco Rubio, but continues to beat Texas Sen. Ted Cruz and former Florida Gov. Jeb Bush.
