Ah yes, the white working class hate that the minorities will have a chance to elect people of their own race. Very progressive of them.
You don't need a majority minority district to elect a minority candidate. See SC-Sen, UT-4, TX-23 is 75% Hispanic and they have a black representative. People don't necessarily vote based on who looks like them. I mean for next year, I'm a Hispanic college student supporting a black candidate for NH-1
Steve Cohen is better representative of Memphis black community then many black candidates would be. And, following your reasoning, why "progressives" are so incensed (look at dKos, for example), when most of whites prefer to vote for one of their own (usually - white Republican), and are in no hurry to embrace present day heavily minority-oriented Democratic party??? They behave very pragmatically and logically (according to you) - vote for one of their own... Of course, time may come when this white vote will become insignificant, but so far - you have Trump exactly because of that reason (these people were fed up with national Democratic party politics, and demonstrated it in such (may be - foolish) way). Democratic Party became "too minority oriented" and "too politically correct" for many of it's former solid supporters... And not only in Deep South (those left it long ago), but in many other areas. Though the best example i know of is still in the South - small, rural Liberty county in Florida. More then 75% Democratic in registration, all Democratic on local level (so, it's willing to elect Democrats, but - different Democrats...), and - less then 20% for Hillary in 2016 (with 75% for Trump)
