his illness while traveling to gain support.
his shortage of campaign funds.
his strong anti - german sentiment.
his disagreement with henry cabot lodge.

Explanation:

Henry Cabot Lodge, a leading Republican senator, strongly opposed the League of Nations, especially Article X which he believed would force U.S. involvement in foreign conflicts. He led the opposition in Congress, successfully preventing the U.S. from ratifying the treaty to join the League, which was the major factor weakening Wilson's proposal. The other options were not the primary cause of the proposal's failure.

Answer:

his disagreement with Henry Cabot Lodge.
