Democrats were told to 'grow up' by one of their own this weekend, as Democratic National Committee chair candidate Raymond Buckley gave a frank assessment of what went wrong in 2016.

Buckley, the chair of New Hampshire's Democratic Party, noted Saturday at the DNC Future Forum in Baltimore, Maryland, that while he's known for being one of the openly gay candidates for chair, he also grew up among the 'lowest of the white working class.'

The candidate suggested that the Democrats' holier-than-Trump approach didn't work, especially in attracting white working-class voters.

'When you are running hundreds of millions of dollars worth of commercials telling the voters that, "Oh, our opponent is offensive," when you are worrying about your damn paycheck, when you are worrying about your job, where you're going to live, whether your kids are ever going to go to school,' Buckley began. '

'They don't give a crap if the president is an insult dog,' he said.

DNC chair hopeful Raymond Buckley told Democrats to 'grow up,' after the party ran a holier-than-Trump campaign in 2016, which didn't resonate with Buckley's white working class voters

Raymond Buckley said that working class white voters didn't care that Donald Trump was an 'insult dog' because they were more worried about their paychecks and kids' education

Buckley said the Democrats 'did not offer a positive message to anyone I ... am related to.'

'We did not offer a message to my neighbors, we did not offer a message to the people in Indiana or Ohio or Pennsylvania or Kentucky,' he added, pointing to the states nominee Hillary Clinton lost throughout the Rust Belt.

What the Democrats did do, Buckley stated, is say 'how offensive.'

'Grow up,' he shouted.

'That is not reality for most of America,' he said.

Buckley is among 10 candidates who are vying to be the next leader of the Democratic Party, which lost the White House and didn't make enough gains to overtake the Republicans in the Senate and the House.

The race will likely come town to the two bold-faced names in the group, Rep. Keith Ellison, D-Minn., and former Labor Secretary Thomas Perez.

Ellison has the backing of former presidential hopeful Sen. Bernie Sanders and other progressives, while Perez has been endorsed by a number of people aligned with former President Barack Obama and the party's last nominee, Hillary Clinton.

Perez got the endorsement of former Vice President Joe Biden earlier this month.

But that hasn't kept the other candidates from gaining notoriety.

Beyond Buckley's outburst, Sally Boynton Brown, who's currently the executive director of Idaho's Democratic Party, said she thought part of her job would be to shush up other white people and get them to check their privilege.

She suggested that those volunteering and leading the party needed to have 'training' to have hard conversations about race.

'We have to teach them how to communicate, how to be sensitive and how to shut their mouths if they are white,' she said at a similar panel discussion, which took place late last month in D.C.

Since that forum, the race has grown from seven to 10 candidates.

South Bend, Indiana, Mayor Pete Buttigieg is also running, along with South Carolina Democratic Party chair Jaime Harrison, media strategist Jehmu Greene, NAACP Veterans Committee Chair Robert Vinson Brannum, Milwaukee-based attorney Peter Peckarsky and Ohio activist Sam Ronan.

Rep. Debbie Wasserman Schultz, the Democrats' most recent DNC chair, received a lot of criticism for seemingly favoring Clinton over Sanders in last year's Democratic primary.

Clinton went on to lose the White House to now President Donald Trump.

Wasserman Schultz stepped down from her position on the eve of the Democratic National Convention in Philadelphia as part of the fallout from the committee's email hack, which now looks to be at the hands of Russia.

Since then, interim chair Donna Brazile has been in charge of the party.

Democrats will choose their next leader later this month.
