Blago's attorney has already announced that he will appeal the only conviction. The Government has already said they will retry him on some of the charges. Still, 3 out of the last 4 governors of the State of Illinois have been convicted of crimes commited in elected positions.
I think in the end, enough of the jurors believed that what Blagovich was doing, to trade for campaign contibutions for his choice of who was going to replace Obama that while wrong is just real life politics, not really illegal. I also think many people don't like wiretaps and snooping on phone and so on for such persons (but ok for Terrorists or murderers).
Perhaps we need to see a national standard for the replacement of resigning/dead US Congressmembers or Senators on the states to reduce the bargining we saw here. Yes, the Governor can make proposed appointments, but perhaps State Legisgative committees should hold hearings of potential canidates, then then State legisgature would approve the final choice. This would remove the bargaing power of the Governor as well as give the people via their reps a say in clearing and approving of replacments.
