It can do at least three things if it doesn’t want to knuckle under. BTW, this is what states must do if the federal government itself doesn’t strike down or repeal ObamieCommieCare:
1) A state's highest court could "underrule" (as opposed to overrule) a federal court decision,
2) Along the same line, legislatively, a state could nullify an abhorrent and unconstitutional federal law, mandate, or regulation,
3) The last resort for a state that has reached the point where it has suffered as the Declaration of Independence calls it, "...a long train of abuses and usurpations, pursuing the same Object...[of]...absolute Depostism..." it can and should divest itself of and cede from the federal government.
Texas can do all of this... then watch as Texas begins to lose federal funds for various ‘projects’...
Although, Texas (and Texans) could probably survive without federal funds for many projects.
Um, actually, in Texas, we have another way of putting the last point.
“When a government has ceased to protect the lives, liberty and property of the people, from whom its legitimate powers are derived, and for the advancement of whose happiness it was instituted, and so far from being a guarantee for the enjoyment of those inestimable and inalienable rights, becomes an instrument in the hands of evil rulers for their oppression.
When the Federal Republican Constitution of their country, which they have sworn to support, no longer has a substantial existence, and the whole nature of their government has been forcibly changed, without their consent, from a restricted federative republic, composed of sovereign states, to a consolidated central military despotism, in which every interest is disregarded but that of the army and the priesthood, both the eternal enemies of civil liberty, the everready minions of power, and the usual instruments of tyrants.
When, long after the spirit of the constitution has departed, moderation is at length so far lost by those in power, that even the semblance of freedom is removed, and the forms themselves of the constitution discontinued, and so far from their petitions and remonstrances being regarded, the agents who bear them are thrown into dungeons, and mercenary armies sent forth to force a new government upon them at the point of the bayonet.
When, in consequence of such acts of malfeasance and abdication on the part of the government, anarchy prevails, and civil society is dissolved into its original elements. In such a crisis, the first law of nature, the right of self-preservation, the inherent and inalienable rights of the people to appeal to first principles, and take their political affairs into their own hands in extreme cases, enjoins it as a right towards themselves, and a sacred obligation to their posterity, to abolish such government, and create another in its stead, calculated to rescue them from impending dangers, and to secure their future welfare and happiness.
Nations, as well as individuals, are amenable for their acts to the public opinion of mankind.”
The EPA, these days, is the priesthood of Global Warming.
If they do, I'm moving South.
