Democrats divided ahead of Bernie Sanders' 'Medicare-for-all' bill release

Senate Democrats are set to announce a new push for single-payer healthcare on Wednesday featuring several 2020 hopefuls touting legislation from Sen. Bernie Sanders, I-Vt., to expand Medicare to everyone.

But divisions remain in the Democratic caucus over whether government-run healthcare may be going too far. Some of the most vulnerable Senate Democrats running for re-election in 2018 are not offering a warm embrace of the policy.
