"You're going to have ten candidates more or less talking about your needs and not the needs of working people," Sanders told SiriusXM's Progress Channel.
Sanders made it abundantly clear he stands in opposition to the Republican candidates' shared agenda, which for him and his growing crowds of supporters just isn't worth discussing.
"They want to give more tax breaks to millionaires and billionaires at a time when the rich are getting much richer," he said. "They want to cut or privatize Medicare, cut Medicaid, cut education, cut the environmental protection agency."
It's not just the issue of money in politics. Sanders, who is one of the Senate's biggest opponents of the Keystone XL pipeline, is just as frustrated that climate change isn't receiving more attention among the GOP hopefuls.
"There may be one or two there who actually have listened to the scientific community and think that climate change is real. Most of them refuse to accept that, and none of them are prepared to act aggressively to transform our energy system," he said.
Sanders' standing up against the "billionaire class" has helped garner record-breaking crowds of supporters at campaign stops this summer as he heads into what many believe will be a face-off with former Secretary of State Hillary Clinton for the Democratic presidential nomination.
