I'm not sure I understand why the "clown" scoring political points is so bad. Where in the rulebook does it state that doing the right thing must be completely devoid of agenda or beneficial byproducts?
Take, for example, volunteering. There are many who "volunteer" because they have to - whether it be for school, punishment, whatever. Do you think the volunteer organizations care why the volunteers are there as long as they work and do their jobs? No. They're just happy they've got people to help.
I think the same thing applies here. I never met Aaron nor do I know how he would react, but I know many folks who care deeply about this issue. They really only care that someone is asking the pointed questions and holding the DoJ accountable. They don't much care who it is or why he's doing it. If the end result is the same, what does it matter anyways?
