I'm not going to waste my time with Dave's app when David and the team are eventually going to crunch the official numbers. Everything below is pure analysis.
This diary has been posted to DK Elections, an official Daily Kos sub-site. Please read the DKE Mission Statement. Our focus is on electoral politics rather than policy or preference. Welcome aboard!
No major changes:
1: White majority. Gohmert (R). Safe Republican.
4: White majority. Hall (R). Safe Republican.
11: White majority. Conaway (R). Safe Republican.
13: White majority. Thornberry (R). Safe Republican.
16: Hispanic majority. Reyes (D). Safe Democratic.
19: White majority. Neugebauer (R). Safe Republican.
Slight changes:
15: Hispanic majority. Now goes up into Seguin (San Antonio metro). Hinojosa (D). Safe Democratic.
28: Hispanic majority. Cuellar (D). Loses the southside of San Antonio and gains Metrocom areas (much more Republican). This district is probably better suited to his Blue Dog tendencies. Safe Democratic.
34: Hispanic majority. Successor to the 27th, except without Corpus Christi. Safe Democratic.
Major change:
27: Hispanic majority (? - apparently). Farenthold (R). Now based in Corpus Christi and Victoria. Lean-Likely Republican.
No major changes:
3: White majority. Johnson (R). Safe Republican.
5: White majority. Hensarling (R). Safe Republican.
26: White majority. Burgess (R). Safe Republican.
30: African American plurality. Johnson (D). Safe Democratic.
Major change:
6: Hispanic majority (? - apparently). Joe Barton (R) should have been a team player. The result of not playing nice was that Smith screwed him with a Hispanic district. He could probably win for a few more cycles, but after Hispanic turnout reaches a decent threshold he's a goner. Tossup.
12: White majority. Kay Granger (R). This district sheds the outer areas and focuses on downtown Fort Worth and its environs. Granger can no longer take reelection for granted. Likely Republican.
24: White majority. Kenny Marchant (R). This district sheds the southern Hispanic areas to Barton and the new 33rd. Much safer for Marchant now. Safe Republican.
32: White majority. Sessions (R). Sheds the Hispanic areas west of downtown Dallas to Barton to make Sessions much much much safer. Safe Republican.
33: This new district is white majority, but has a size-able Hispanic minority which could alter the outcome of any election. Wendy Davis could run here and win. I'd place this at lean-likely Republican now and lean-likely Democratic later this decade.
No major changes:
7: White majority. Culberson (R). Are they waiting for the sky to fall in? The sizeable and growing Hispanic minority here (his district is probably non-VAP Hispanic majority, just not VAP yet) will eventually make it tossup, but for now: Likely Republican.
8: White majority. Brady (R). Safe Republican.
9: African American plurality. Green (D). Same as previous, basically. Safe Democratic.
18: African American plurality. Lee (D). Same awful windmill shape. Safe Democratic.
29: Hispanic majority. Green (D). Loses the Republican areas of the district. This was IMO a likely D district which is now: Safe Democratic.
Minor changes:
22: White majority. Olson (R). Loses Galveston area and gains most of Fort Bend County. Safe Republican.
Major changes:
2: White majority. Poe (R). Loses Beaumont. Much safer for Poe (he was already safe, but whatever). Safe Republican.
14: White majority. Paul (R). Poor Paul. His district shifts towards Beaumont, but luckily is still: Safe Republican.
36: White majority. Awful snake-like district curving around Houston from Beaumont. Likely Republican (wait and see. Beaumont is heavily black, and the areas in Houston it takes in are heavily Hispanic).
No major changes:
10: White majority. McCaul (R). Only lean-likely Republican at the moment, but will probably be tossup by the end of the decade.
20: Hispanic majority. Gonzalez (D). Uh... This district is more conservative than currently by a smidgen, thats it. Safe Democratic.
Major changes:
17: White majority. Flores (R). Wow. They moved this district southward and into Austin by shifting the Doggett's 25th into Burleson (south of Fort Worth). Safe Republican.
23: Loses the part of Laredo that it had. In the process it become more Republican. Canseco (R). Lean Republican.
25: White majority. Doggett (D). Ugh. What a bitch move. This district only takes in the streetcar suburbs of Austin and then snakes through western Travis county (conservative) and up toward Fort Worth (conservative). Doggett's a goner. Likely Republican.
31: Carter (R). White majority. Contracts into just Williamson county and Bell county. Safe Republican for now, likely later in the decade.
35: Hispanic majority. New district which will probably be filled by someone from Austin, not San Antonio.
This map is awful.
