The last ten years has witnessed a marked rise in the use of a different left and center-left ideological term in America: progressive. This rise has been so pronounced and widespread that "progressive" is now the most favorably viewed ideological term in America, surpassing both "moderate" and "conservative."

"Moderate" (another weasel word) Republicans often call themselves "progressive." Mainstream liberals often call themselves "progressive." Democratic Socialists and others who used to call themselves "radical" now cling to "progressive."

No wonder it's popular.
