Do people living in the south of U.S. think that Wisconsin have accents?

Yes, people living in the south of the U.S. often think that people from Wisconsin have accents. The Wisconsin accent is characterized by a number of features, including the use of "eh" as a question tag, the pronunciation of "o" as "aw," and the pronunciation of "oo" as "ooh." These features are often seen as being distinctive and non-standard, and can therefore be perceived as an accent by people from other regions. Additionally, the Wisconsin accent is often associated with rural or working-class populations, which can also contribute to the perception that it is an accent.
