Not sure about MS and GA but aint no way TX is a toss up. You have dallas, austin and houston (the whole area not just city) that is slightly blue due to the city itself. For example the whole houston area is about 50-50 inside city and outside city limits. The rest of the state is solidly in the red with a few small pockets that is kinda balanced.
Anyone got a grand to lose I will make that bet.
