You people are not paying enough attention to US politics and I understand why since it takes time and effort and is not what you do for a living (I assume).
A Federal judge has ruled that the Congress can force aids of the President to testify under oath to Congressional committees. The new left is gearing up to try Bush and company for war crimes after O is elected. This left is not the left of old on the major ideological latent space of American politics. They want to change the system and put their leaders in charge. Their shock troops are lawyers, judges, academics, the media and the new wealth from IT and Wall Street speculation. They expect support from the Euro left. It is a type of “soft power” Nazism with pro Islam against the nefarious Jews. It is anti conventional religion with a secular religion of greening and multiculturalism in place of the old religions.
They are not Marxists but they have borrowed some Marxist/Leninist ideas.
I believe that they will succeed in destabilizing the country for a while. But they will not win. Another anti-system coalition will emerge and it will have force and arms behind it. I can not at this time guess as to where their leadership will come from.
