Nothing in history shows that what you're saying is true. Women's Suffrage was won without the vote, by definition. Civil Rights was won with black voter turnout at an abysmal 25% to 7% depending on the state. When the Civil Rights movement forced concessions from the government, it was bi-partisan. And when the government redoubled their efforts of white supremacist dominance through the war on drugs and racialized mass incarceration, it was a bi-partisan effort. Nothing has ever been won because more people voted in primaries. Nothing has ever been won because do-nothings were voted in to buy time.
