Is there any other issue where there's such a dramatic disconnect between politicians and regular people? A majority of the country supports legalizing marijuana; I doubt more than ten or twenty Congresspeople do.
Most political issues.
Which political issues? I can't think of any other issue with majority popular support that doesn't have the support of one or both parties or at least significant factions of the parties. I don't think there are more than ten representatives in the House, meanwhile, who support marijuana legalization.
90% of America supports universal background checks and that failed. 60% supports raising the minimum wage; no progress there. While marijuana is one of the most underrepresented issues in congress, they fail again and again to produce results that America actually wants.
