Temporary fix, at best. There are only about 4 million of them and then Haiti is empty. There are 500,000,000 Hispanics of various shades to import.
When word gets around to the Haitians that the Dems want their vote but then want them to be consigned to the housing projects, the welfare system and eventual slaughter (as an inferior race) by Planned Parenthood, some may decide that Haiti is not quite as bad as their assigned spot in America.
Not 4 million, about 11.4 million.
