Despite their efforts to win over black and Latino voters, both Hillary Clinton and Bernie Sanders have shown no progress in hiring minorities within their own campaigns.

The staffs for both Democratic presidential candidates went on a hiring spree since last October; however, a new report published by Inclusv -- a diversity hiring initiative project powered by PowerPAC -- reveals the contenders failed to hire people of color.

Inclusv Executive Director Alida Garcia told Latin Post that the Sanders campaign has more than doubled by the end of 2015, growing from 193 in October to 418. However, only 30.9 percent of his staff is of color, which is down slightly from 33 percent in October. Meanwhile, 13.4 percent of his staff is black, while 11.7 percent of his operatives are Latino. The Sanders camp also self-reported that people of color comprise nearly 37 percent of his senior staff.

According to self-reports by the Clinton campaign, her camp has over 30 percent of people of color and 37 percent of her senior staff identify as being of color. This shows the amount of minority hires in her campaign has pretty much remained the same since October, when 32 percent of people of color were working for her.

Inclusv, which helps professionals of color get hired in Democratic campaigns, says Sanders and Clinton have remained committed to self-reporting its hiring data, but it had hoped for better results.

"While Inclusv applauds the transparency of the campaigns, we are disappointed that these numbers show a decline in racial diversity on both campaigns," said the group in a statement sent to Latin Post.

"This is especially troubling given that African Americans are expected to be over 50% of the turnout in South Carolina's February 27th primary, and Super Tuesday will include states with high percentage of voters of color, including Georgia, Texas, and Virginia," it added.

Likewise, Garcia urged the candidates to "do better" when it comes to hiring minorities.

"We believe that campaigns that are 70% white don't reflect the voters and values of the Democratic Party and it's incumbent on both campaigns to fight for increasing staff diversity the same way they fight for endorsements by well-known people of color," she told Latin Post in an email.

In a statement, Garcia also encouraged people of color to contact her organization if they wish to work on one of the Democratic campaigns.

"As the Sanders & Clinton campaigns pivot toward South Carolina, Nevada, and Super Tuesday we encourage them to approach their hiring processes with greater transparency and intentionality and we encourage people of color who wish to work on these campaigns to upload their resumes at Inclusv.com so that we can continue to advocate for them," she said.

In response, Bernard Coleman, Clinton's chief diversity and human resources officer, reassured voters that "The Hillary for America campaign is committed to diversity, inclusion, and equity."
