Grant - another white guy from the distant past? Unlikely. American patriot? Again, unlikely.
It'll be Dutch Morial, or the like.
You are closer to local thinking than you realize. NO WAY can it be anyone white, unless...someone suggest a monument to the great Landrieu himself. If enough time passes after he is out of office, I could see a statue of him somewhere. There are ‘monuments’ to Trayvon Martin-types everywhere and every day on the streets of N.O. Dead bodies, black men mostly, left on sidewalks as a reminder that ‘black lives matter’. It will be some generic ‘symbolic’ monument or a black person-no matter how obscure.
Yeah, the Grant memorial would be a big keg of whiskey.
