MO was more Democratic then. It was also a strong Perot state.
In addition to MO, there would be a lot of other states (AR, KY, TN, WV) that would be more Democratic today if the party hasn't taken such a left turn 20 years ago. In addition to the loss of electoral votes, that's ten Senate seats gone. And becomes that much harder for the Democrats to control the Senate (which BTW confirms nominees for the Supreme Court) on a long term basis.
That is not why these states swung R. National Dems ran more left wing campaigns in the 1980s and 1970s than they do now, though perhaps that could change in the 2020s.
