The chairman of the State Democratic Party says he hopes Jean Carnahan will run for the US Senate in her own right when her temporary, two-year term ends. Joe Carmichael of Springfield doesn’t see a party blood-letting once Mrs. Carnahan fulfills her appointment to replace her late husband, Mel Carnahan. Carmichael says he will suggest Jean Carnahan run for the seat in her own right. Others have suggested some top Democrats will be vying for a chance to run for the seat.
