The ad hominem attack of mental illness accusations used to quell or impeach a political dissident. In extreme cases it leads to the medically unnecessary comital of the dissident to a mental institution and/or the forcing of the dissident to take pacifying or punitive medication.

It is also effective when the dissident has inherently eccentric behavior that can be magnified by the frustrations of dealing with the government's accusations.

A derogatory term used to mock supporters of Ron Paul.
1)Used to kill off rational discussion in hopes that the "Paultard" won't call them on it. This has proven very ineffective against Ron Paul himself.

3)Used by business owners who receive federal funds to curse those who would dare take away their cash cow.
4)Used by residents of the Washington, D.C. area to curse those who would make them take a job in the private sector.
Darn it. Those Paultards are going to make me get a real job.
