IN: Is it true that does putting on a horse shoe hurt the horse?

Shoeing, when performed correctly, causes no pain to the animal. Farriers trim the insensitive part of the hoof, which is the same area into which they drive the nails. This is analogous to a manicure on a human fingernail, only on a much larger scale.

IN: Is it true that do supreme court rulings apply to all states?

The Supremacy Clause of the United States Constitution (Article VI, Clause 2) establishes that the Constitution, federal laws made pursuant to it, and treaties made under its authority, constitute the supreme law of the land. It provides that state courts are bound by the supreme law; in case of conflict between federal and state law, the federal law must be applied. Even state constitutions are subordinate to federal law. In essence, it is a conflict-of-laws rule specifying that certain federal acts take priority over any state acts that conflict with federal law. In this respect, the Supremacy Clause follows the lead of Article XIII of the Articles of Confederation, which provided that ''Every State shall abide by the determination of the United States in Congress Assembled, on all questions which by this confederation are submitted to them.'' A constitutional provision announcing the supremacy of federal law, the Supremacy Clause assumes the underlying priority of federal authority, at least when that authority is expressed in the Constitution itself. No matter what the federal government or the states might wish to do, they have to stay within the boundaries of the Constitution. This makes the Supremacy Clause the cornerstone of the whole American political structure.
