You are the aedile
As aedile, it's your job to ensure that grain gets to the city and is properly distributed and at a fair price. But there's been a bad few years at the harvest; now grain is sparse and you need to import more.
A group of grain merchants have suggested that if you lower duties and grant priority to grain ships on the major shipping lanes, then they could bring grain into Rome faster and more plentifully.
What will you, the aedile, do?
Take a law granting special benefits to grain merchants to the tribal assembly
Consult the Senate on the law
Discuss the matter with your political allies
