Well, I wouldn't be presumptuous enough to tell anyone what to do. There's no reason that the opposition can't operate on parallel avenues of attack. The Dem's certainly do. There's a chance that the birther route may be productive. I personally think that O's going to have to get a good deal more unpopular before the courts start doing anything about it.
On the other hand, the stench surrounding the question, and O's inaction on the matter could very well be synergistic with all of the other shenanigans happening at the same time. To me, it appears that the court of public opinion may be far more effective in kneecapping “The One”, than what has been happening in the court of law. I'm not saying that it shouldn't be used, but the most effective results may come from a direction not originally contemplated. Could be bad PR will work the best, or it may be something that no one expects. Keep working that angle, but don't lose your situational awareness. Boresighting is useful, but many become unaware of occurrences on their flank.
It is fascinating how well information has been suppressed (lots of effort there for whatever reason). One would have thought someone would have blabbed already, but the Dems chokehold on political power is probably worth removing “inconveniences” to some of them, which makes people rather hesitant to stick their necks out. Yeah, there's lots of folks that know the truth, but most aren't going to risk their lives to clarify matters.
