During the cold war , what were the us 2 main concerns?

The main concern of the United States and the other western powers during the Cold War was that the Soviet Union would obtain control of the Western European countries through either invasions or by communist takeovers of unstable governments. Neither side was ever directly engaged in a full-scale armed combat, and the doctrine of mutually assured destruction, or MAD, prevented either faction from using their heavily armed nuclear arsenals. Psychological war, propaganda, proxy wars and espionage were the primary means of each side's struggle for dominance in post-World War II Europe.

i believe the answer is:

-   william jennings bryan is a democrat while mckinley was a republican

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
