Obama will not defend the US Constitution. He will Destroy it.

Amendment 1 - Freedom of Religion, Press, Expression. Ratified 12/15/1791. Note

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

Obama and the Democrats will enact the Fairness Doctrine which will severely curtail opposition media on the radio.

Amendment 2 - Right to Bear Arms. Ratified 12/15/1791. Note

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

Obama wants to keep individuals (the people) away from owning guns. He does seem to want to have a civilian militia but I guess if you're not a part of it, you don't get to keep your gun.

Amendment 4 - Search and Seizure. Ratified 12/15/1791.

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

The PATRIOT Act is not likely to be repealed.

Amendment 5 - Trial and Punishment, Compensation for Takings. Ratified 12/15/1791.

No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.

Obama wants to take more taxes. And abortion is deprivation of life. Care to compensate for an aborted baby?

Amendment 9 - Construction of Constitution. Ratified 12/15/1791.

The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.

Obama believes that those rights not enumerated by the Constitution can be assumed by the federal government.

Amendment 10 - Powers of the States and People. Ratified 12/15/1791. Note

The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.

Obama believes that abortion "Freedom of Choice Act" is something that must be decreed on a federal level. Unfortunately, it isn't up to the federal government.
