Indiana and Missouri will go Lean D before Georgia does.
Why on earth would you think that? Even today, state elections and presidential vote are often different. The demographics in Georgia are near perfect for Clinton to pick up that Republican state.
Missouri and Indiana, on paper, are demographically perfect for Trump. Trump is just not blowing out Clinton in those two states because of the national climate and both states have Republicans who are willing to vote for Democrats occasionally.
The whites in Georgia are far less elastic.
