MORAL OF THE STORY:

"Never send a monkey to do a man's job."
~ Captain Leo Davidson
CATO at least is solid libertarian on economic issues. Therefore, they are going to get behind hands-off govt execs & legislators and their going to slap the hands of tax-and-spend types.
(You don't have to know "all truth" to recognize a tax-and-spend governor, do you?)
