The media went bonkers when some conservatives spent enormous amounts of time trying to prove Clinton killed Vince Foster. That didn't amount to anything either.
There was also a movement of people, including Jerry Falwell I believe, that were convinced Clinton was part of some massive drug trafficking scheme. The media loudly attacked people advocating that as well. The issue went nowhere.
Just because you can get under the skin of the media doesn't mean the issue is a good one for our side.
I didn't see Clinton hiding any information about Vince Foster.
Obama had consistently refuse to release his long-form birth certificate. There is only one reason for that -- because it either doesn't exist or there is something on it that he doesn't want made public. Either way, it is legitimate issue to ask why he won't show it and what he is covering up.
