He strikes me as the exact opposite type of lawyer that Dr. Taitz is. That is, that he's not willing to put numerous unsound and piece meal type lawsuits together (as they've been described by many) and hope that one sticks. He seems to be the kind of attorney that will represent another in the near future, but one that has a better chance of succeeding based on all lesson's learned to date. And yes, much of his "pontificating" has been very educational (ex. Chester Arthur research, QW research, etc) to the country. Anyway, that's my take on the difference.
Donofrio hasn’t done anything since his own case was shot down except criticize and bloviate.
Those are good and true points you made about Leo.
