There is a new president. He is a republican. Mr. Dorr is probably in the clear unless there is a current investigation pending and it will be referred to the new U.S. Attorney after the Grand Jury looks at it. If the Grand Jury looks at it, it's been investigated by a Federal level investigator and they are famous/infamous for the quality of their investigations.
The last prosecutor was a democrat. He took his marching orders from Washington D.C. If there was any chances of embarrassing a republican, charges were filed. I can't say the same thing for who ever the next prosecutor is but he will be a republican appointee. I can only hope if charges are viable, the Grand Jury will vote to indict. I don't know much about Mr. Dorr or the IGO. I have no idea where he/they stand on any issue except that apparently they are pro 2nd Amendment. He may be a dick head or he may be a nice guy, I don't know. I talk with my local elected representative in the House if I want him to know how I feel about any particular issue. I think he cares what I say to him about issues that are important to me. We have known each other for a long period of time and we tend to know how each other thinks. I really don't need the IGO or Mr. Dorr or any other organization speaking for me. I get a little worried when someone else starts "speaking on my behalf" without me being there.
Mr. Sorenson and the Ron Paul employees who paid him off and got this whole issue in front of Judge Pratt, had to of known they were playing with fire. In this case, they all got burned. Mr. Sorenson plead guilty to his charges hoping for a plea bargain that would keep him out of jail. He lost. The other 3 players went in front of a jury of good Iowa citizens who got a chance to hear all of the evidence and in the end they lost also. That's the way the game is played. The only winners in this whole deal is the attorneys. They get paid either win or lose.
