I can't help but feel that all of this is only part of the 9/11 backlash, and that by the time a new president comes in, traditional domestic issues will again take precidence and these things will fall by the wayside. Look at the Civil War when Lincoln illegally imprisoned people. This was a measure taken in a dangerous time, and when things calmed down, it no longer occurred. One could argue that terrorism is a permanent issue, but I can see it not being a big deal in maybe 10 years or so.
Remember when we had all of those anthrax scares? How long did it take for that to blow over? There hasn't been an attack in the US since 9/11, and if it stays that way through, say 2010, I say we won't have any worries about losing our rights per se, but more worries about our privacy in general in a world where personal data is so heavily recorded, and our every move will be tracked. The issue will be general privacy from corporations and the government, not restrictions of speech.
I think Cynical is being a bit too conspiratorial. Criticizing the president is the trendy thing to do in America. All the kids and their favorite celebrities/pop punk bands are doing it.
