What is the main conflict in Winterset by Maxwell Anderson?

With its combination of "low" prose and "high" poetic verse, which enables it to be sharply realistic while simultaneously commenting on universal philosophical themes, Winterset is widely considered Anderson's best verse drama. Its ambitious political and philosophical agenda, as well as its elegant poetry, earned Anderson the Drama Critics' Circle Award of 1936. The style of Winterset has inspired many critics to compare the play to a Shakespearean tragedy.
