I doubt that a hurricane landfall 40 days before the election will have much impact, especially in Florida where they’re pretty used to it. But one of the provisions of the Electoral Count Reform and Presidential Transition Improvement Act of 2022 – which is one of the best things Congress has passed in decades – addresses a particular piece of malfeasance that could have occurred previously.
Specifically, previous statutes had a “failed election” clause that said that if voters failed to make a choice on Election Day, then the state’s legislature could award that state’s electors. But the language was so broad that Florida Republicans could have easily used lingering impacts of a hurricane as an excuse to declare a Harris popular vote win as a failed election and unilaterally award the state’s EVs to Trump. The new statutes only allow the state to “modify the period of voting as necessitated by force majeure events that are extraordinary and catastrophic.” So Florida could extend voting beyond election day in that narrowly defined circumstance, but the electors would still have to be awarded based on the results of the popular vote in the state.
