Macron doesn't strike me as the brightest bulb, but if the Democrats had put up anybody like him, they would likely have won in the US as well.
Not the brightest bulb? The guy graduated from two of the most prestigious universities in France, has worked in several high profile positions both in the government and in the private sector, created is own political movement, and got elected president at 39. I don't know what you need.
Besides, if you speak French, you may want to look at his interviews on mediapart (paywalled). The guy is reactive, has well-thought ideas on complex issues, and explains them clearly. But yeah, you have to go beyond soundbites.
