Scary but true.
Dr. William Black explores this issue at Naked Capitalism and Washington's Blog takes it up in a detailed analysis.
The way I learned it, the "founding fathers" created the separation of powers--the judicial, legislative, and executive branches of government--to combat the potential for tyranny.
We already know how corporations can influence political elections and thereby have the potential to corrupt both the legislative and executive branches.
Now we learn that corporations can also influence judicial elections.
So, our government's 3 branches of power can now easily be corrupted, legally, by corporate power.
Any anyone who calls this tyranny might be labeled a terrorist and disappear without recourse into some secret CIA prison.
