Article 4 ABUSE OF POWER
The President misused and abused his office and impaired the administration of justice.
The President made false and misleading public statements for the purpose of deceiving the people of the United States;
The President made false and misleading statements to members of the Cabinet and White House aides;
The President frivolously asserted executive privilege;
The President made perjurious, false and misleading statements to Congress (answers to 81 questions).
You could substitute Vice President for much of this particularly the “I am neither beast nor fowl” contention on the use of classified information.
If nothing else the impeachment of Cheney, which will have broad public support, will give Congress the capability to investigate many of the hazy issues such as Iraq, Classified Documents, Wiretaps, Contracts, etc…
Once these guys leave office in January 2009 it would be nice to have something of our Republic left.
