One of the most powerful beliefs in modern politics isn't a policy. It's the belief that nothing can change.

You hear it everywhere and I feel it too. Most of us do.

It often begins with surprisingly small groups of people connected in the right ways, reaching a tipping point that makes what seemed impossible suddenly feel inevitable.

Not as a motivational slogan but as evidence. Because throughout history, some of the biggest shifts in politics, economics and culture looked impossible right up until the moment they happened.
