I want to know the answer to the following question:
Which region of Tennessee swung in favor of secession in the June 1861 referendum?
All the background I'm provided with is that "In February 1861, secessionists in Tennessee's state government—led by Governor Isham Harris—sought voter approval for a convention to sever ties with the United States, but Tennessee voters rejected the referendum by a 54–46% margin.". Is that enough to answer the question?
