Topeka ? Former U.S. Rep. Jim Ryun made it official Monday, filing to try to reclaim the position he lost in 2006 to Democrat Nancy Boyda.

Ryun, who now lives in Lawrence, will face State Treasurer Lynn Jenkins in the Republican Party primary on Aug. 5.

Ryun was a five-term congressman when Boyda defeated him by a 51 percent to 47 percent margin. Boyda, of Topeka, is seeking re-election. The general election is Nov. 4.

The 2nd congressional district runs from the northeast corner of Kansas to the southeast corner, and includes western Lawrence and Douglas County, and all of Leavenworth, Ottawa, Topeka, and Manhattan.

Ryun said the top concerns of voters are the economy, tax relief, immigration, and reducing the cost of gasoline.

He said his positions haven’t changed — he supports making permanent President Bush’s tax cuts of 2003, the construction of a fence on the U.S.-Mexico border, and increasing oil exploration, including drilling in the Arctic National Wildlife Refuge.

He said his loss in 2006 had a lot to do with the fact that Democrats at the top of the ticket — in the governor’s race and attorney general’s race — won by large margins.
