The problem is sin. It isn't poltiics. It isn't even some of his secondary wrong doctrines except where they downplay sin.
There are many wrong conclusions that will be drawn about this.
He was political. That was his downfall! No! Sin was his downfall.
He had a mega-church. That was his downfall. No! Sin was his downfall.
He had some errant secondary doctrines. That was his downfall. No! It was the primary doctrine of sin that was his downfall.
Sin is the disease of mankind. But that IS NOT AN EXCUSE! It condemns us all. If this man becomes repentant, he will be honest and willing to accept his self-inflicted consequences for the good of us all and in recognition of God's righteous standards. Only that kind of repentance is of the saving variety.
What he has done is throw into doubt the genuineness of his saving faith. Whether he accepts the consequences of his own sin will reveal more on that subject.
You don't think its a coincidence that these scandals keep occuring with these same type of teachers? Baker, Swaggart, Bob Tillman, etc. Seductive prosperity gospel, social gospel(political activism) signs and wonders (Haggard is part of the new Apostolic propehts/vineyard movement- see deceptioninthechurch.com).
I think your post should have waited until the investigation proved or disproved Haggard's innocence.
