How did the differences between presidents Harding and Coolidge influence their presidencies?

Both were Republicans, but they did have some key differences that should be noted. Coolidge was much stricter on immigration, an d had nearly twice as many deportations under his governance. Coolidge also had much more spending, while Harding reduced the national deficit and did not spend as much. Inflation, however, was much higher during the Harding administration, which reflected his overall spending and budgeting policies.

Both of those presidents are pretty conservative in their policy.

The main difference might be their attitude with foreign trades.

Pesident Harding is very determined in secluding United states from foreign trades which ending up in worsening relation with other nations in europe.

President Coolidge on the other hand, is pretty open minded about the foreign trade, but he still had to face the negative effect from Harding's decision.
