The Springfield News-Leader takes a look at the latest candidate, Mike Moon of Lawrence County:
Moon, a membership coordinator for St. John's Hospital's fitness centers, said he's fed up with the federal government becoming increasingly large and involved in the economy and people's lives.
"Our country's in a big mess, and I think we need strong leaders in Congress to stand up for what's constitutional," Moon said.
If elected, Moon said he would hold a principled line against government programs that are not specifically defined in the U.S. Constitution.
"If it doesn't fit, I don't think it should be implemented or employed," said Moon.
The three leading candidates at this point appear to be Sen. Jack Goodman, R-Mount Vernon, Springfield auctioneer Billy Long, and Sen. Gary Nodler, R-Joplin.
