You did a great job before, and I'm sure you will do a great job again (assuming you are elected... but you seem to have a way of "discouraging" people from running against you
).
As far as micromanaging goes, I agree with you in concept, but you may have a hard time doing that for a little while. You may get a nice even number of spt... then our Golden Age ends. You balance it out again... and then a factory is built. Finally every town is how you want it... and we complete Hoover Dam.
In all seriousness, I haven't been doing an awful lot with our core lately. If we are building 80 shield items, then 20 spt is great. More often it ends at 22 spt or something. It is almost impossible at this point to find the 5 extra shields to get to 27 spt, so I've been leaving things at odd numbers like 22. You are right that the core towns aren't growing in general, so there are not a lot of adjustments on a regular basis.
However, I would encourage our next President to take at least a quick pass through all of our corrupt towns every turn (or as often as you can stand to). We want to emphasize food in those towns and hire as many specialists (of the right type!) as we can. When those towns grow, the governor will almost invariably put the new citizens on low food/high shield tiles. When a worker or settler is built, the governor reassigns citizens poorly.
There are really only two things to look for in those towns:
1. Try not to waste food. If a town only needs a couple food to grow, then maybe it can get an extra specialist for a turn or give a high food tile away to a neighboring town and still grow.
2. Never work tiles that provide less than 3 fpt. If we can't get 3 fpt from any tile, then the citizen is only supporting himself and should be a specialist instead.
Good luck to whoever wins!
