[WS:] I do not think it is that important. The persona of the POTUS may be important for the electoral circus, but it does not mater for big business, because no matter who gets elected, he or she will do what "the markets" demand.
If Brenner (_The Economics of Global Turbulence_) is correct, the rise of speculation results from secular declining profitability of investments in manufacturing. This is a global systemic problem, so the outcome of local elections (even in the US) does not matter, especially that to date no political party (right or left) has been willing or able to go against the wishes of "the markets" - at least in OECD countries.
