“I am announcing my run for governor to reimagine this Commonwealth,” Allen said. “Imagine state government that in a crisis jumps in and activates all of our talents in response. Imagine one Commonwealth where those who are in power recognize their responsibility to the greater good and where those who feel powerless are reconnected to their own agency through communal action. That’s what democracy is about: coming together, working together, learning together, deciding together, and acting together.”
