Shouldn't the republican party be worried? If the trend continues and a lot of companies move from California to Texas bringing along a lot of liberal employees with them, won't that tip the already narrowing margin towards the democratic party?
Isn't it pretty well known in the finance world that using stale public information to predict the market is a fool's errand?
Unless you have some kind of specialized non-public data (e.g satellite images of number of cars parked outside parking malls, number of cargo ships moving in and out), trying to predict the market with historical data does worse than "Just give me some monkeys, darts and a dart board".
