Problem is systemic corruption, mimartin. ACORN is at best incompetent and irresponsible and has been demonstrated to be so in more than just the last presidential race. Hell, Lewis was purportedly brought in/elevated to clean a lot of it up. Apparently she may not be cut out for it. As to the answers to your series of questions, as corrupt as you think ACORN is.
Btw, not saying that every corrupt organization axiomatically means that every employee is inherently corrupt. The IRS is corrupt, as is Congress, but it doesn't mean that every member of the organization is as well. Same goes for unions and every kind of human organization you can probably think of (including scientists and religious leaders).
