St. Louis County Prosecuting Attorney Bob McCulloch added his name Saturday to the list of Democrats endorsing Sen. Barack Obama, D-Ill., for president.

 In a statement, McCulloch said, “Barack Obama is the right choice for this country.  He knows we need to invest more in our local law enforcement in order to build healthy and safe communities for our kids to grow up in.  He’s committed to giving local officials the tools they need to protect Americans.”

McCulloch was among those attending Obama’s rally Saturday night at the Edwards Jones Dome. The fire marshal and Dome executive director Bruce Sommer estimated the size of the crowd at about 20,000.
