Here's why:
* Multiple "Dear Mr. President" works: There are several books, poems, and songs with this title.
* Literary devices vary widely: Different authors use different devices and to varying degrees.
* Counting devices is subjective: Some devices can be subtle, making it difficult to decide if they're intentionally used.
To help me give you a better answer, please tell me:
* The full title of the work: (e.g., "Dear Mr. President: A Letter to My Country" by Bill Clinton)
* The author: (e.g., Langston Hughes, if it's a poem)
* The type of work: (e.g., poem, novel, song)
Once you provide this information, I can give you a more accurate and helpful response about the literary devices employed in the work.
