The most partisan state senate districts

For LA, you can get an 88.1/10.2 R district almost from just Livingston parish alone:



Its much less compact, but this rural gerrymander would be 90.0/8.7 R:



And a this New Orleans district is 97.1/2.4 D:

^ Really? 75% McCain seems low for TN. The Republican votes seem more consistently dispersed there than in other states, though.

Yeah, eastern TN is very consistent.

Actually, though, if you do a Memphis-area district that hugs the western border, you can get it up to almost 77%:

And most of the states that have white majority D areas are going to be states with very little minority areas anyway. ME, NH, VT, ID, WY, UT, probably IA (though not 100% sure). That Alaska district is majority native Alaskan though. Minnesota, Oregon, Washington, and Montana will probably have majority white D districts (MT and OR don't have election data, unfortunately) too.

To comment on Arkansas, I was surprised to see how Republican the northern end of Lonoke County is. Its consistently ~78% McCain. I didn't even try to pull one in the NW, but someone could try.

NW AR seems to be a lot like eastern TN - the R votes are pretty evenly spread out and less polarized than in the rest of the state. Lots of precincts were in the high 60's/low 70's. This one is 75.7/22.0, which is about the most I could get:
