In theory, yes, but I actually doubt many businesses are making hiring decisions based on whether a D or an R is in the White House, and certainly not on a longview political strategy. It isn't the way businesses think. Certainly conservatives would have us believe that every time a D is in the White House, businesses worry about increased regulations and stop hiring. They said this about Clinton as well. If it were true, you'd expect macro-economic data to show a better economy with the R in the White House as opposed to the D, over time, but that isn't the case. Clearly, businesses are making their decisions based on whatever is profitable in the moment, an equilibrium between demand and supply. Whoever is in the White House or Congress is at best a secondary consideration.
To be sure, some business people will CLAIM that they aren't hiring because they worry about regulations since this providers conservatives with an anti-regulatory talking point, and obviously the businesses would rather not be regulated. But that isn't the same thing.
