She completely checked out after the recall and doubled down on the boondoggles. Why bother working if you can travel the world for free? She knows there is no downside for her and she probably can parlay her time as mayor into a Morial-esque job with some national org when she's out.
On the bright side, there is probably some benefit gained for us too - in the same way that an orange cone was better than Jason David, "no mayor" is largely better than "Latoya as mayor." The city certainly hasn't gotten any WORSE since she quit working.
