What was the main concern of the portion of roosevelt's audience that supported the united states' involvement in the conflict?

A main concern was a major loss in popultion. They lost so much people because Roosevelt got involved in the Eurpoen conflict. Then it lead to faincail and money problems to people doubting Roosevelt. They were concern if He would hep other countries.

Hope this helps!
