This quote by Napoleon Bonaparte suggests that in politics, being unintelligent or oblivious is not a downside. This indicates that even if someone is not particularly well-informed or smart, they can still achieve success in politics. This might be because politics is often more about charisma and manipulation than it is about intelligence. It might also be since politics is frequently about making choices that are popular with the general public, rather than choices that are necessarily the most logical or beneficial. This quote could also be analyzed as a cautioning to those in politics to not underestimate the power of the unintelligent or ignorant. It might be a tip that even if someone is not particularly knowledgeable, they can still have a considerable impact on the political landscape.
"Well, I think any time you delve into this sort of religion, politics, as you well know, you're going to, you know, touch a few nerves. I wasn't - now - and this is the honest truth"
