The Republicanism of the Missouri legislature

[Kevinstat]

For most of the 20th century, Missouri's Democrats were in St. Louis, Kansas City and the rural Southern part of the state.

The rural Southern party of the state swung Republican with the rest of the South.

St. Louis and Kansas City have been stagnating or declining in population for the past several decades and exercise less and less clout within the state.

Not southwestern Missouri though.  I think that has long been Republican like northwestern Arkansas.
