'Malpractice' won't fly (sadly) because the bastards will have the defence that they aren't professionals (true enough, too), and the US Code makes that a requirement for the crime.
Have to find some different statutes, I'm afraid.
I thought the pertinent charge with regard to elected officials was "Malfeasance in Office".
Why wouldn’t a treason charge help?
Let us take Murtha; he condemned a group of marines acting within their ROE in a warzone, before an investigation had concluded, on national television. (Appearing on TV is not the execution of the duties os a legislator; neither is the rendering of judgments of a war-crime... and even if it was, doing so without an investigation is incompetence in the extreme.)
Treason is defined as adhering to the enemies of the US, or giving them aid or comfort. Murtha aided our enemies by:
1) Needlessly destroying troop morale.
2) Condemning, without trial, our fighting men.
and
3) Legitimizing the illegitimate resistance of our enemies. (According to the Geneva and Hague Conventions uniforms are a must.)
Further: How is Cap and Trade, or the treatment of the GM/Chrysler bond-holders NOT either Conspiracy against rights OR Deprivation of rights under color of law?

Both of those are capitally punishable crimes.
