The DA may let him off the hook for political reasons but it supports a lot of peoples perception that the Caster campaign was very mean spirited and didnt care about the law or distorted personal attacks on anyone who stood up to Bill. It's funny how he says this is "worse" campaign--his mudslinging and his lies--the ones we now know about and the ones we may never know about were the issue.
Caster never liked playing by any rules but his own.
