Nathan Deal has not yet revealed specific plans for his second term — those details will come this week during several speeches he is prepared to deliver, including Monday’s inaugural and Wednesday’s the State of the State address — the broad aspects of his agenda become clear in his last go-round as Georgia’s chief executive, and likely his last hurrah in politics. With that in mind, state lawmakers have acknowledged Deal is likely to swing for the fences in his final term as he tries to burnish a legacy that has, at times, been dogged by charges of unethical behavior.
