No, the executive branch is SUPPOSED to not have much real power
No, the executive branch is SUPPOSED to not have much real power. Bush, Cheney, and their goons are doing everything in their power to expand the power of the executive branch beyond what the Constitution allows. That should scare you, regardless of the accuracy of this particular article.
If you are not scared by this, take a moment to read about the FISA Amendments Act of 2008, or any other of the myriad violations of the Constitution committed by the current administration. The executive branch was never intended to have this type of power and the balance needs to be shifted back towards the legislature and judiciary.
