Im hearing that they had a 10% failure rate thus far. 10% of 1,782,281(yes I looked this up and this is 2008 numbers, no doubt its higher today) is 178,228 that were turned down. Those checks that are not being sent out could easily add up to $356,000,000 (guestimated 2,000 dollars a month per leach for welfare and food stamps) You can do a lot with savings like that.
Even Fox News is reporting the 2ish percent figure:
I hope the OK law isn't modeled after the FL law because that one is costing taxpayers money, NOT saving money.

Please don't assume a TANF recipient receives a sum of $2000. That's insane:

You also forgot to include the cost to reimburse all applicants that pass the test, as 30-35 dollars each, as well as other administration costs, not forgetting the legal defense of this law.
