This announcement is more of a shot across the bow than anything else. This won’t pass in it’s present form, but don’t fool yourself. Eventually bits and pieces are going to become law.
Consider the long game being played here:
2008: Socialism? Fuggetaboutit!
2012: Bernie who?
2016: Bernie Sanders? Tell me more!
2020: Senator Bernie Sanders -D (VT), Chairman of Senate Budget Committee.
