It has been noted here that Pat Sajak has written two opinion pieces for Human Events. However, not being a regular visitor to Pat's web site, I didn't know that he regularly shared his opinions until I read this article in the New York Post today. I don't know if Pat's pieces technically constitute a "blog" but they're interesting reading nonetheless.
Fair warning: most, but not all, of the columns are political in nature.

To avoid repeating the recent unpleasantness, I'll end with a completely apolitical example: here is a wonderful piece about Johnny Carson and the time when Pat almost subbed for him.
