Candidate uses only his first name on campaign sign

Here's a link http://www.bus.umich.edu/NewsRoom/ArticleDisplay.asp?news_id=18011 to a great article about a guy names Rick Snyder who's running for Governor of Michigan. 

He's only using his first name on his campaign signs.  This is great.  He's got a very good reason too.  Read the full article; the sign quesiton comes last.

Michigan's primary is August 3rd, 2010.
