Confirmation of Role of Risk in Public Moral Failure

I first heard about the concept of risk being a factor in public moral failures at least seven years ago when I heard John Ortberg speak at a Leadership Summit. Just last week, this concept was re-enforced while reading an AP article in the Tennessean about the moral fall of Tennessee Senator Paul Stanley. The article noted that University of Virginia political science professor Larry Sabato believes politicians are born risk-takers who have a propensity to stray (Mark Sanford, John Edwards).   I haven’t studied all the evidence to say for certain I agree with this connection, but it sure seems logical and obvious to me.  I am certain these same dynamics can apply to ministers who are not yielded to the Holy Spirit.
