Clarksville, TN – Democrat Kim McMillan says she's dropping out of the Tennessee governor's race to run for Clarksville mayor. McMillan's announcement today leaves Jackson businessman Mike McWherter as the lone serious Democratic candidate to succeed term-limited Gov. Phil Bredesen. McMillan's decision followed an announcement by Clarksville Mayor Johnny Piper that he will not seek re-election. McWherter, son of former Gov. Ned McWherter, this week made a $1 million contribution to his campaign. McMillan, meanwhile, has struggled to keep pace in campaign cash.
