My guess, from reading his comments, is that said political affiliation is a moot point; Irrespective of which way you sway, Mr. Barkley is asserting (at least how I interpret it) Dems only express concern for the black contingent at a time when it is most beneficial to them. Do Republicans do the same? Yes, to a degree I suppose, but I do feel Dems are a bit more frisky when it comes to to the "ohh, white rich people"- this and "ohh, brown people" -that tropes during the election cycle.
