Florida lawmakers are introducing bills on how to implement Amendment 4, which adjusted the Florida Constitution to restore voting rights to felons who’d completed their sentence. But what once seemed like a moment of triumph for civil rights advocates might soon become the prelude to a new legal battle.

The passage of Amendment 4 in November was the culmination of several years of community engagement and grassroots activism. And it paid off: The ballot initiative to restore voting rights to ex-felons passed with nearly 65% approval, a heralded outcome in a state known for its razor-thin margins of electoral victory.
