Jonathan Turley sums up the problem:

Obama has now again betrayed the civil liberties community and lifted the threat of the veto. Americans will now be subject to indefinite detention without trial in federal courts in a measure supported by both Democrats and Republicans. . . This leave Ron Paul as the only candidate in the presidential campaign fighting the bill and generally advocating civil liberties as a rallying point for his campaign. Paul offered another strong argument against the Patriot Act and other expansions of police powers in his last debate. He also noted that the Patriot Act provisions were long advocated before 9-11, which was used as an opportunity to expand police powers. As discussed in a prior column, Obama has destroyed the civil liberties movement in the United States and has convinced many liberals to fight for an Administration that blocked torture prosecutions, expanded warrantless surveillance, continued military tribunals, killed Americans on the sole authority of the President, and other core violations of civil liberties.
