Recent reporting on mayoral candidate Bill de Blasio's early activism shows that he visited Nicaragua in 1988 (on a humanitarian trip to deliver medical supplies), and was part of various groups in the US sympathetic to the Soviet-backed Sandinista government -- particularly as they fought off the US-backed Contra rebels. So: Does any of this matter? Does de Blasio's activism of 25 years ago indicate a core philosophy as his rivals have charged? How much does the context of the late-1980s Cold War activism matter?
