Topeka ? Gov. Kathleen Sebelius will make official Friday what most Kansans have assumed would be the case: She’s seeking a second term.

Sebelius, elected in 2002 over conservative Republican Tim Shallenburger, will make her announcement during a noon news conference on the Statehouse’s south steps, her office said Wednesday.

Spokeswoman Nicole Corcoran said the governor won’t announce her running mate then, but still plans to do so by the end of the month.

The No. 2 spot opened up when Lt. Gov. John Moore announced last week that he was retiring from politics after his term ends in January.

No other Democrat has announced plans to challenge Sebelius in the Aug. 1 primary.

Six Republicans are running for the chance to challenge her in the Nov. 7 general election, including Sen. Jim Barnett, of Emporia; Ken Canfield, of Overland Park; and former House Speaker Robin Jennison, of Healy.
