The 1920 presidential elections of the USA were dominated by the subject of America's role in world affairs.

Option C

Explanation:

During this period, the country had joined the organization ''League of Nations'' which was formed to maintain peace in the world, under the presidency of Woodrow Wilson. While, the nation was suffering from worker's strikes, recession, and racial riots. The incumbent president Woodrow Wilson faced challenges as he was perceived to be more focused on world affairs.

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
