A lot of State budgets are stressed due to Federal mandates and programs such as Medicade.
Unfunded mandates, a really good reason to gen up support for nullification.
Medicaid is neither unfunded nor a mandate.
Not to mention we have more than just the constitution to go on. We have multiple writings by the founders from Before and after the constitution.
We also have their actions when actually governing to consider. For some reason those don't seem to get as much attention, e.g. Washington federalizing the militia to put down an anti-tax uprising, Washington and Madison chartering a national bank, and Jefferson, oh, Jefferson.
You know, in those days the schism was between Hamilton's Federalists and Jefferson's Democratic-Republicans. The Federalists,
like Hamilton himself, embraced a fairly broad interpretation of the general welfare clause. The Democratic-Republicans took a more strict constructionist view. Indeed, the Jefferson quote in your sig is a paraphrase of Jefferson's description (in a
letter to to Albert Gallatin) of this philosophical difference between the two parties.
Five years after writing that letter, now President, Jefferson was put in the odd position of spending a large sum of money in pursuit of an action not unambiguously authorized by the Constitution. The Federalists, their power dwindling at this point, argued against the Louisiana Purchase on constitutional grounds (such naked opportunism!). What did Jefferson's Democratic-Republicans present as a counterargument to justify their purchase? Why, the general welfare clause! Here's a leading Democratic-Republican in the House, Caesar Rodney,
making the case:
A recurrence to the Constitution will show that it is predicated on the principle of the United States acquiring territory, either by war, treaty, or purchase. There was one part of that instrument within whose capricious grasp all these modes of acquisition were embraced. By the Constitution Congress have power to "lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defence and general welfare of the United States." To provide for the general welfare! The import of these terms is very comprehensive indeed. If this general delegation of authority be not at variance with other particular powers specially granted, nor restricted by them; if it be not in any degree comprehended in those subsequently delegated, I cannot perceive why, within the fair meaning of this general provision is not include the power of increasing our territory, if necessary for the general welfare or common defence.
Four years later that fine soldier for the party became Jefferson's attorney general. He retained the post for most of Madison's first term.
Politics wasn't invented after the founding generation died. Nor was selective (and sometimes internally inconsistent) interpretation of the Constitution's vague language. Welcome to America.
