Is it a flip-flop on Cheney's part, or simply a reflection of changes in the law?

Four years ago, the U.S. Supreme Court had not yet struck down the Texas law against sodomy (which some might term "gay sex") on federal constitutional grounds of "equal protection."

By ruling in that manner, the Supreme Court may have created a Constitutional precedent that prevents letting each state regulate homosexual conduct...including marriage. If the states cannot regulate gay marriage, then it is impossible to allow each state to decide for itself.

If so, it is hardly a "flip" on the Vice-President's part to recognize that the law has changed and amend his policies and/or viewpoint accordingly.
