Democrats have a formula-- a recipe for success in Louisiana elections. Demographer Greg Rigamer explains.

"You need, as a Democrat, to win 90% of the African American voter and a third of the white vote," Rigamer said.

And African Americans need to account for at least 30% of the votes cast.

"That's been the formula that has held true for every every race since really 2003," he added.

By now, you have no doubt heard that on Saturday night, Governor John Bel Edwards won re-election over Republican challenger Eddie Rispone. 

But how did the Democrat incumbent score victory in ruby-red, Louisiana?

To talk through the results, I'm joined by demographer and Edward's campaign consultant, Greg Rigamer.
