Nothing new. The US is continuing to implode as it has been doing since 1945. Nobody in that time was won any election of any significance without massive support from corporations and the wealthy. In terms of general policy, it really doesn't matter who gets elected. That was clear during the presidential campaign as Obama became a darling of Wall St.
The US long ago decided on a policy of world "leadership". It's a nice word to cover an ugly truth. If everybody must follow the leader, then how can any country have a democracy that means anything at all? Indeed, the closest allies of the US have been puppet dictators - the Shah of Iran, the King of Saudi Arabia, the dictators of central America.
If you google The Project For the New American Century, read its statement of purpose. It is to spread "American values" (torture, invasion, terror bombing?) around the world for American economic benefit. And, for an example of who gets the benefit, look at Haiti. It has been under the control of untrammelled American capitalism for almost a century, through American-sponsored dictators and American military government. That's why it is the poorest country in the western hemisphere. That's why Haiti's President Aristide was exiled by US troops. He was going to spend money in silly ways, like hospitals and schools. That's why the US has never sent its promised aid to Haiti after the earthquake. There is no intention of rebuilding Haiti. The intention is to keep it forever a pool of cheap labour.
The US now needs constant war to sustain its major and thriving industry - weapons. In good days, before the crash, that meant free trade (with free meaning American business was free to exploit and contol countries before they could develop their own industries.) But now it's bad days. So watch as "free" trade gradually became "fair" trade - meaning the subject countries much now admit American products free, but imports to the US will be taxed with customs duties to protect big donors to the Democrats and Republicans.There will also be a renewed drive to privatize public services like water, sewage, and education.
The Tea Party has no answer to any of this. It hasn't even asked the question. All it wants is a return to traditional values, most of which, like most of American history, never existed. The US Constitution was never intended to create a democracy - except within the limits of a two party system in which both parties were actually the same. It was also a system to exploited racism (against Blacks, and Native Peoples, and Mexicans, and Latin Americans in general, and Hawaiians, and Phillipinos, and now Moslems) to keep power in the hands of the rich. (Check out the incomes and slaves and landholdings of good ol' boys like George Washington and Andrew Jackson.) Tea Partyers are just the latest suckers to try to guess which shell the pea is under.
The US has been rotting inside since 1775. The Tea Party is just one more, small step away from reality for American voters. American leadership (world dominance by military force) is what it has always been about. Now, with even the pretend capitalism that the US lives on, war is all the more necessary. If ever Islam is defeated, American corporate leaders and the propagandists they call news media will just have to seek another bogeyman.
Once upon a time, we Canadians were the bogeymen. I expect we will be again. Been there. Done that.
