In hindsight, the legislature damn well should have done so instead of letting it fall into a quirky courst system. The ultimate example of judicial activism.
The federal Safe Harbor law on elections states that if it isn't resolved by the 7th day before the Electoral college meets in a manner in accordance with the law in place prior to the election, that the State Legislature may pick the electors for their states any way they want. Thus, it didn't come into play until midnight Dec 12th. The Florida State Legislature had prepped everything and was ready to go, but couldn't act until after that deadline - or they'd be changing the law and thus be inviting the USHoR to ignore the electoral college ballots.
