She wasn't an underdog in the Congressional contest, and ended up performing far below her GOP predecessor, Dan Miller, getting only the barest minimum base GOP vote despite drastically outspending her Clintonista 'Rat opponent. The problem for her is that she has not run a statewide contest in 8 years. What worked for her (pre-2000) was that she was unknown, and that is no longer the case. Given that she never had the opportunity to effectively gauge support because she couldn't run for a 2nd term as Sec of State in '02, there was no way to tell how well she would've done AFTER being a very known quantity (again, only using the Congressional race as a gauge, it was very poor). Her polling against Nelson, who remains very low-key (and has worked well for him (like a pre-2000 Harris)), has been absolutely abysmal. It's not the polling data that is flawed, because the same polls by the same company show Nelson losing to Jeb by at least 10%. Harris has failed to turn around perceptions and she just needs to cut her losses and run for her House seat again... there are far worse consolation prizes than that.
I'm sure KH's Campaign Manager Ed Rollins (who orchestrated Ronald Reagan's campaign) will appreciate your advice.
Are you an expert on TN politics as well?
She still won, didn't she?
