Most Americans want President Donald Trump and his 2020 presidential rivals to release their taxes, a new HuffPost/YouGov survey finds.

Americans say, 56% to 27%, that Trump should release his tax returns to the public. Among those who want to see the president’s taxes, a majority say it’s very important that he make them available. Other recent surveys have foundsimilarly robust support.

Trump’s continuing refusal to release his returns is a break in precedent from most presidents since Richard Nixon.

“The public has no right to see those,” Hogan Gidley, the White House principal deputy press secretary, told Fox News on Monday. “Congress definitely doesn’t have a right to see the tax returns of a private citizen, but also just think about the precedent that sets. Listen, this was already litigated. ... It’s never going to work.”

The Democratic chairman of the House Ways and Means Committee formally asked the Internal Revenue Service last week to hand over copies of Trump’s personal and business tax returns from the last six years.

There’s no clear public consensus on what Trump’s returns might actually show: 30% believe they would reveal information about his finances so serious it would prove he is unfit to be president, 22% that they would reveal information that’s less serious but still politically harmful and 27% think they would show nothing untoward at all. The rest aren’t sure.

Unsurprisingly, Trump’s opponents are the most convinced that the president has something to hide. Eighty-four percent of voters who backed Democratic rival Hillary Clinton in the last election suspect Trump’s taxes harbor damaging or disqualifying information, while about a quarter of Trump voters say the same. Most Clinton voters also think Trump isn’t as rich as he says that he is.

Americans’ desire for transparency isn’t limited to Trump: Those polled also say, 58% to 23%, that they’d like to see Democratic candidates for president release their tax returns.

But, perhaps largely due to Trump’s high-profile stance, the issue of access to candidates’ tax returns is deeply polarized.

An overwhelming majority of Clinton voters say they want to see tax returns both from Trump and from his prospective Democratic rivals. By contrast, just 28% of Trump voters think the president should release his taxes and just 38% want to see his Democratic opponents do so.
