I'll float one of my usual wrong theories here. It is true that the Clintons were not used to being defied. They had all the power of the Government, and vast resources of private investigations to brutally retaliate against those with whom they were displeased.
However, shall I say, business is business. While Hollywood and the major networks were "in the tank" for Clinton, it cost them money, big time. Now, perhaps, there is a chance to make some of that money back. The first shot at profiting off the Clintons may be fired with this series. After that, there may be more, ALOT more.
The Clintons were about so much that Hollywood adores. I mean just think about it. Raw ruthless power, greed, drugs, oodles of sex, violence, cowardice, political intrigue. There are so many possible stories to do on the Clintons and so much money to be made that perhaps the gloves have come off. There's gold in them thar Clintons, and the rush might be on.
I think you got it.
I'll add a related point: One of the most essential elements in the Clinton's power is/was FEAR. Trying to block this program, and FAILING to do so, takes that fear away from others as well. Once the fear is gone, and it becomes clear that money can be made, the stampede will begin.
This line of reasoning may even explain why ABC decided to run the story: The moonbat wing of the Democratic party is now in control of their party, and these nutcases are very down on Hillary for continuing to "support" the troops in Iraq. For many of these lunatics, bringing down the Clintons is a way to further cement their control of the Democratic party.
