Maybe I'm overestimating Bush's performance somewhat, but I don't see how Carter could do much better than this.
Carter - 34.2 - 271
Bush - 33.9 - 157
Perot - 30.7 - 110
Other - 1.2
Perot overperforms his actual '92 results outside of the South - people are even more disillusioned with their choices. Carter only hits 50% in GA, AR, LA, and WV; 45% in TN, NC, SC, KY, MS, AL, NY, MA, RI, MD; 40% in TX, FL, MO, OK, OH, IL. He manages 35-40% in CA, MI, WI, IN, VA, NJ, DE, PA, and CT but still loses them.
...no.
