It does sound somewhat unconstitutional but so is stealing two national presidential elections. I guess our fates are tied to the Republican courts. Sleep easy everyone.
Justin Raimondo has it about right:
The ultimate expansion of the "unlawful combatant" definition to include any and all opposition to the War Party, whether military or political, is only a matter of time, and not much time at that. This administration and its allies have long maintained that their critics are "objectively" aiding the terrorist enemy. If Iraq is the main theater of our war on terrorism, then criticism of the war effort, such as organizing an antiwar demonstration, amounts to "material support" for "hostilities against the United States." . . .
