A federal judge on Saturday issued a scathing rebuke to Florida’s top election official in an order canceling a hearing on a lawsuit over vote-by-mail ballots. U.S. District Judge Mark Walker accused Florida Secretary of State Ken Detzner of delaying a hearing on the lawsuit “so that he could use every second available to run out the clock” so there wouldn’t be enough time to address problems raised in the lawsuit. The judge also said Detzner’s actions amounted to an “undeclared war” on the right to vote in Florida, the largest swing state in the presidential election. The judge in Tallahassee, Fla., said he would make a decision on the lawsuit without a hearing that had been set for Monday.
