In a word: nothing.
I have spoken with several American friends and acquaintances and all have bought into the new "Hope" and "Change". No, this is not the Hope and Change of the Obama regime, but the Hope and Change of the Republicans, the other branch of the One Party Two Branch system of government. Simply put, it is now the American right that is mindlessly chanting Hope and Change, egged on by the oligarch owned mass media and cheering on one side or another of the One Party Two Branch state.
In truth, few stop to think through what will change and but they have lots of hope, hope that constantly gets redirected away from direct action and in hopes that discredited elections will work this time...always this time...thus the owners of America put off any real opposition and street protest or worse for another 2 years and another 2 years, while the prols mindlessly hope for change that never comes.
Am I saying that there are no conservatives who will be elected? Of course not. What I am saying is that it will not matters and for several key reasons:
First, the Republicans may win the majority of both houses of parliament, but it will be a narrow majority. The exiting Democrats are prepared to push through many laws before they get replaced. The sitting Republicans will do next to nothing to stop this, as most are on board of the same express train as the exiting Democrats and opposition is just political theater for the masses.
Now, the Republicans will not only not have a large enough majority to over ride a presidential veto, but to believe that the Republicans will act conservatively is a delusion. Conservatives will not only be a minority but as new members will have no seniority and even less say. Then there is the issue of corruption and sell outs. It is thus, equally foolish not to believe that at least some, if not the majority of, the new conservatives will sell out as soon as the big money is thrown at them: which will be about 10 minutes before they reach their offices.
Lastly, is of course the principles on which these so called conservatives are coming into power. These are not what the anglos call paleo conservatives who believe in balanced budgets, really small government and no foreign wars. No the majority are rightly classified as Neocons, would be "conservative" would be president Sarah Palin, falls right into that.
Sure they want to cut spending, but on the citizens who are already unemployed. They will be the hatchet men for the Democrat wing, while continuing to spend on foreign imperial wars of revolutionary Third Way Socialism (Corporate Marxism aka Capitalism).
They will continue to spend and spend and bomb and bomb, just on slightly different subjects, while making soft sounds to calm the narrow sighted masses with a fight against gay marriage, while actively supporting Islamic Jihad against Christians world wide. Further, they are almost all Free Trade zealots, thus they will not bring factories or jobs back, which is the only way to hold off the continued collapse in the US economy.
Thus, any investors, who still believe that the US will turn around, just after this election or the next or the next, are equally fooling themselves, in no better fashion than the masses duped into an election process controlled by their owners and made into grand political theater.
