Having Larry Klayman involved in this matter will guarantee that it is not treated seriously.
All it takes is one competent attorney (flawed though he/she may be) who can put the burden of proof on Barry and the DNC to prove his eligibility and then run the case up to SCOTUS for a final definition of NBC.
You may not take Klayman seriously, but if he files good papers in court, Barry and the DNC must respond and must continue to make indefensible arguments (indefensible in a trial on the merits with discovery) supporting his natural born citizen status and the authenticity of his HI LFBC. Klayman is not Taitz, IMO.
