What is the main conflict in Sunrise at Campobello by Dore Schary?

The moment when the conflict is at its greatest intensity in the play, comes in the final precious minutes before FDR is to appear on the platform. He nervously adjusts his braces with the help of his son, and Sara arrives in a show of support. She expresses her concerns regarding the "howling mob outside," and there is a predictable moment of apprehension between mother and son. Up to this point, tensions have been building between them over FDR's future in politics. However, when FDR defends the proceedings as being typical, Sara takes an unexpected tack, telling him it is "hardly the time" to give her "lessons in politics." She simply wants a moment, she tells her son, to say "God bless you." This final show of support serves to erase any conflicted feelings FDR has harbored earlier. There is a clear break in the tension that was mounting earlier in the play. It is a turning point marked by Howe, who acknowledges Sara's gesture as a peace offering in their otherwise verbally charged relations, quipping that Sara resembles a career politician.
