The Supreme Court "threat" and propaganda is just another tactic using the politics of fear utilized by the ruling class to coerce and control the working class for the purpose of maintaining the status quo of moving further to the right all the time in favor of, and for the protection of, the ruling class.
The ruling class uses this threat against all party candidates in the electoral process. Why? To keep the electorate focused on everything other than the single issue that effects all issues: class warfare of the (capitalist, elite) ruling class against the working class.
Stop and consider that the same Supreme Court threat is used by the Republicans against Secretary Clinton ... and was especially used against Senator Sanders when he was a potential candidate of the Democratic Party. This tied directly into the threat of "socialism" for those on the right.
The politics of fear only benefits the ruling class.
The working class needs to stay focused on the real issues that determine our day-to-day life: income inequality, racial injustice, gender injustice, climate change, never-ending war, childcare, healthcare, the injustice of the entire global capitalist economic system, etc.
Your boss at work that just denied you and your co-workers an increase in wages for the third year in a row doesn't give a damn on how the Supreme Court ruled on its latest case. Your capitalist boss just cares about keeping wages (your wages) low in order to improve his/her profit.
