The Mechanism for any vague nullification of an as of yet unmentioned Federal law, would have to take the form of the nullification participation by Multiple States.
I.E., it would not be just Texas. Misery loves company.
The Health Care “attempt” with its long fuse of “not effective until 2012” (don’t worry be happy) would give 50 states a long timeline to react violently with “State rights” laws (Legal or NOT). After all, the Courts move slowly when laws are reversed.

So Perry and Texas, “Threatened” with a most excellent Idea for fighting Maxist laws passed in a hurry, and it helped slow down the Marxists and get cheers at the Tea Parties, but it was just a bluff, a threat, and the MSM picked it up (as designed) and spread the “ridiculous” threat.
MSM can be manipulated, and Texans can threaten DC, if DC threatens Texas.
Montana and Tennessee have voted to nullify federal gun laws.
