GOP House pick-ups in CDs that had been Democratic since before the 1990's

[Southern Senator North Carolina Yankee]

Does anyone know approximately when any of these districts were last represented by a Republican?

How does one define this when CD boundaries in other-than-at-large states change over time?  All parts of the district in prior decades?  Any part of the district in prior decades?  The CD with the same number, regardless of whether it moved within the state?

Tracking Hal Rogers seat back to the 1883, it has been held by a Republican continuously except for the 1933-35 term. During that period it ranged from the 11th, to the 9th, to the 8th, and finally to the 5th.

As for Tennessee

The current seventh (Blackburn) was actually the sixth prior to 1982.

The Eight was renumbered the seventh in 1972. The then sixth was reconfigured to oust a liberal Dem by the Conserva-dem legislature, and it elected a Republican. That seat, after being renumbered the seventh in 1982, has been solidly Republican ever since. Another Dem seat was eliminated in 72 appearently (what was then the seventh held by Roy Blanton). In 1982 the state regained a seat.. Beard's sixth became the seventh and Ed Jones was placed back into a district numbered the eighth.  That established we can go back to 1953 through Fats Everett to Jere Cooper. Cooper represented the ninth prior to 1953, and the eight once again prior to 1943, and the ninth yet again prior to 1933. Finis Garret and then Rice Pierce take the seat back to 1897.

I would say 1872, or basically Reconstruction when the 8th, and 9th were both held by Republicans.

AL-05 is another one, the GOP hasn't held since reconstruction, but gained last December when Griffith switched parties.

AR-01 is "unreconstucted Dem" seat (alteast it was till 2010, ) It was also Blanche Lincoln's.
AR-02 was held by a Republican from 1979-1985 and again from 1989-1991.

Before Larkin Smith held MS-04 (it was the fifth then actually), it was held by Trent Lott for 16 years.

MO-04 was last held by Republican in 1953.
MN-08 was last held by a Republican in 1947.

On a related note, are there any non-urban districts that have a Democratic streak of at least 30 years?

It depends on what you define as an "urban" seat?

WV-03 probably is one.

Aren't there majority-black rural districts in the south?

Well, thats where its important to know what the standard is. MAny of them include heavily black urban precints like AL-07 includes black precints in Birmingham and Montgomery. SC-06, I beleive, includes parts of Columbia, SC. MS-02 probably would work as would NC-01.

TN-09, LA-02 definately aren't rural. 

You would have to lay out a maximum percentage of residents that live in urban areas to be considered "rural" districts like 20% or less in urban areas or something like that. Then take that threshold and come up with a list that meet that standard.
