Brackkhaven was elected in 2070 and came into power in 2071. He should be up for re-election near the tail end of 2074. The KE contract was signed in 2071, and I want to say it was a four year deal as well, maybe five years. It'll be up for renewal in either 2075 or 2076. I have no idea if players want KE to stay or Lone Star to come back ... upsides and downsides for each.
As for running a game, I always find it handy to put a timeline together. I used to do some minor "A leads to B" stuff, but later I learned how to plan for 'seasons' of adventures, dropping hints and seeds along that get picked up down the line, and, man... HUGE difference maker. If you know that Candy Kane's new commercials for NERPS! will get crazy popular in three months, leading to jingles that you can't get out of your head and record sales, you can lead to this in the game , giving them runs that seem unconnected, but when they're done, they realize that it was a giant puzzle. That kind of thing always has a big effect on players.
Seasons are *fantastic* tools.
