Come and knock on our door: Senate GOP would have three districts meet in Nashville (UPDATED)

The figurative white smoke is rising above the state Capitol as Senate Republicans have announced they will reveal their redistricting maps on Thursday.
The Tennessee Journal has learned the Senate preference is for a three-way division of heavily Democratic Nashville that would entail the 6th and 7th districts currently held by Republican Reps. John Rose of Cookeville and Mark Green of Ashland City, respectively, grabbing portions of the capital city. (This paragraph has been updated to show it’s Rose’s 6th, not Scott DesJarlais of the 4th District, that would move into Nashville).
Green would retain only about a third of Williamson County, the traditionally anchor of the 7th District when now-Sen. Marsha Blackburn (R-Brentwood) held the seat. The remainder would become part of the new-look 5th District that has been held by Democratic Rep. Jim Cooper since 2003.
Rapidly growing Rutherford County would remain entirely within the 4th District, which would likely require an overall westward migration of the seat’s boundaries. DesJarlais is from the eastern side of the district.
The House GOP is scheduled to make its draft congressional maps public on Wednesday amid comments by House Speaker Cameron Sexton that Nashville could be split into two or three districts.
The two chambers have been understood to be at odds about how exactly to go about gaining an eighth seat, so the final shape of the plan could still change.
