Don't get your hopes up. Acorn will weather this just like all the other crap. O's administration and the Congress are rife with people who feel it's alright to screw the "man", regardless of the legal implications.
Most likely they'll throw a few people under the bus for expediency's sake but that won't make any difference in the overall. Do you really think that O or his minion, Eric Holder, will do or allow anything to place such a useful organization in jeopardy? No way! This criminal enterprise will continue to receive taxpayer money to function as the cancer it so obviously is.
