They really don't have one, maybe hope that during a Republican President's midterm there is a stock market crash and the Republicand nominate Scott DesJarlais and then the Dems nominate a moderate, but not Bredesen. Even this scenario is a tossup and the GOP would probably hold veto proof majorities in both TN Chambers. Then when the economy is healing Gov. Moderate Democrat loses badly.
What about the demographics in the Volunteer State ? I'm assuming 15% African American, 4.6% Latino & 1.6% Asian/Pacific Islander
