If this case had come out of a state other than Florida, the federal judge would have only been belaboring the obvious. But Judge Mark Walker knew that Gov. Rick Scott was in sore need of some basic civics. “No right is more precious in a free country than that of having a voice in the election of those who make the laws under which, as good citizens, we must live,” Judge Walker wrote, quoting the late Justice Hugo Black from a landmark 1964 Supreme Court decision. “Other rights, even the most basic, are illusory if the right to vote is undermined.” In this case, Hurricane Matthew had contributed to the undermining. Hundreds of thousands of coastal residents had heeded Gov. Scott’s warning and fled inland as the storm menaced Florida. Government offices were closed. Mail delivery was disrupted. All this as the Oct. 11 registration deadline approached for Floridians hoping to cast ballots in the general election.
