A progressive is somebody that supports policies and programs that actively work towards progress. Progress on the Affordable Care Act would be supporting a universal system of healthcare that doesn't leave 30 million Americans behind. Progress on Citizens United would be comprehensive campaign finance reform and eliminating the influence of money in our political system. Progress on criminal justice reform would be decriminalizing all drugs, ending the drug war, retroactively eliminating the fines and time for nonviolent drug offenders, and allowing actual research to be done into the potential benefits of any/all substances. Etc.
