On August 19, Wyoming held primaries for the Democratic and Republican Parties. Richard Grayson, the only name on the Democratic primary ballot for U.S. House, was nominated with 14,207 votes. Only 190 write-ins were cast for that office in the Democratic primary. Here are the unofficial results.
Richard Grayson has residences in Arizona and New York. He was a Green Party nominee for U.S. House from Arizona in 2010, and he was an Americans Elect nominee for U.S. House from Arizona in 2012. Wyoming is in the Tenth Circuit. The Tenth Circuit ruled in 2000 that states cannot require candidates for Congress to live in that state on filing day, because the U.S. Constitution says that candidates for Congress need not be residents of the state they are seeking to represent until election day itself.
