I think Obama is possibly the most dangerous and destructive president we have ever had. An example is ObamaCare, which is now embattled in the Senate. If that goes through the way Obama wants, we will have something very much like the British system. If the American people have their health care paid for by the government, depending on their age and their condition, they will be subject to a health commission just like in England which will decide if their lives are worth living much longer.
In terms of the Patriot Act, and all the other things he has pledged he would do, such as transparency in government, Obama has reneged on his promises. He pledged to end torture, but he has continued the CIA renditions where you kidnap people and send them to another country to be interrogated. Why is Obama doing that if he doesn't want torture anymore? Throughout Obama's career, he promised to limit the state secrets doctrine which the Bush-Cheney administration had abused enormously. The Bush administration would go into court on any kind of a case that they thought might embarrass them and would argue that it was a state secret and the case should not be continued. Obama is doing the same thing, even though he promised not to.
Obama has little, if any, principles except to aggrandize and make himself more and more important. You see that in his foreign policy. Obama lacks a backbone—both a constitutional backbone and a personal backbone. This is a man who is causing us and will cause us a great deal of harm constitutionally and personally.
