Obama is eager to get federal mitts on school curriculum so the screws can be tightened on what kids learn and (just as important) what they do not learn. He is now welcoming nationalizing of curriculum under the name Common Core. The heart of Obamacare, which Obama's appointees kept reminding us we must obey because it is "the law of the land," was a set of minimum requirements for insurance plans. When millions of nonconforming plans were cancelled, Obama unilaterally created one exemption or change after another without any statutory authority, and he also changed the dates for compliance by employers that had been legislated by Congress. Congress refused to pass the Dream Act, but Obama ordered the same provisions by regulation.
The Constitution makes it the prime duty of the President to "take care that the laws be faithfully executed," but Obama refused to faithfully execute the Defense of Marriage Act (DOMA) which had been overwhelmingly passed by Congress and signed by President Bill Clinton.
These are just some of the ways that Obama "has knowingly and repeatedly violated the Constitution."
