regress - to return to an earlier and usually worse or less developed condition or state
(Merriam-Webster Dictionary, www.meriram-webster.com)
While those on the left politically tend to avoid any connection with the word “socialist’ or “Marxist,” they consider it safer to define themselves as “progressive.” But I would assert that the actions of the left under the Obama administration these last five years have not caused our nation to progress but to regress.
