Progress takes time, baby steps. If you want something, you have to start at the bottom and work your way up. That's the way Bernie Sanders sees it with health care for Americans. Instead of demanding a single payer health care system NOW, like that described in HR 676, a legitimate single payer plan that now has 72 cosponsors in Congress, Bernie thinks it's "prudent" to improve Obamacare first by adding a public option to it, to "work toward" Medicare for all.
