Both Bernie Sanders and Donald Trump are attracting huge crowds during their campaigns, but Sanders says it's the only similarity between them.

"I'm not a billionaire. My family doesn't have a whole lot of money. We are raising our campaign contributions from 350,000 people who are contributing...on average $31.20 apiece," he said to Chuck Todd in an interview on NBC News Sunday.

"I think, that's a little bit different approach than Donald Trump's," Sanders added, according to CBS News.

During his recent campaign at the Iowa State Fair on Saturday, Sanders acknowledged Trump's show of wealth during his whole campaign. Trump arrived at the fair aboard his $7-million helicopter where he let Iowa kids ride for fun. During his speech Saunders joked that he left his own helicopter at home.

"It's in the garage," Sanders quipped. "Forgot to bring it."

"When I speak to 28,000 people in Portland, Oregon, and 27,000 people in Los Angeles, the vast majority of those people, they're not 'registered Democrats.' They are ordinary people who are sick and tired of politics as usual," Sanders said on "Meet the Press", NBC News reported.

Despite this growing number of supporters, Sanders still faces a dilemma with African American voters, who were disappointed with how he handled Black Lives Matter protesters.

Sanders counters that doubt by insisting that "There is no candidate for president who will be stronger at fighting against institutional racism and, by the way, fixing a broken criminal justice system."
