Didn't know Tennessee was on the radar of competitive states in 2004. Was it because of the common polling error in Tennessee of overestimating the D vote? Or was Kerry definitely favored there at one point during the campaign?
TN, AR, and MO were still precarious before the 2004 election took place. Bill Clinton had carried them twice and Bush only won the states by slight margins in 2000, so pundits were unsure how the states would behave relative to the NPV. The final results confirmed TN and AR as solid R states, while MO remained competitive until 2012.
