I have no idea. He has two kids, but he had them when he was a state representative back in the early 90s. I have no idea how old they are now, fourteen years later. He's probably younger than I am (more and more people are these days), but not that much younger, and my kids are grown and gone.
Two possibilities that occur to me are that (1) he had a family business and has sold it. Maybe that coincided with his departure from politics. (2) he worked for Newt Gingrich, and may have quit out of disillusionment when Newt's career blew up over the skirt.
He must have had a good reason. I wouldn't enter politics today as it's too dirty.

I have noticed the same thing. :-)
