Bernie Sanders Bernie SandersThe Hill's Campaign Report: Trump faces backlash after not committing to peaceful transition of power Bernie Sanders: 'This is an election between Donald Trump and democracy' The Hill's 12:30 Report: Trump stokes fears over November election outcome MORE said Thursday that increased support for "Medicare for All" among Democrats is “vindication” that the Vermont independent and Democratic Party are on the same page for some issues.

“Bernie Sanders has been campaigning for lower price prescription drugs, he’s been campaigning for Medicare for All and national health care really for decades,” David Sirota told Hill.TV. “It is a vindication that the Democratic Party, many members of the Democratic Party, are pushing for some of the same things."

Several of Sanders’s fellow Democratic contenders have embraced his Medicare for All legislation in some form, with some even co-sponsoring the bill.

However, Sirota argues that the devil is in the details, saying Sanders is the only one who has fully embraced the proposal.

“Our campaign is very clear about what we’re talking about — a Medicare for All single-payer system that replaces the private insurance system. It’s a very popular program, especially among Democratic voters,” he told Hill.TV.

Some Democrats have expressed support for expanding health care coverage to more Americans but remain divided on how that should be achieved.

Sanders and Harris were the only two candidates who raised their hand during the Democratic presidential debate in favor of abolishing private health insurance for a government run health care option.

Harris later walked back her support of eliminating private insurance, saying she misheard the question.

"I am a proponent of Medicare for All,” Harris said in an interview with MSNBC. “Private insurance will exist for supplemental coverage.”
