Are you said ‘cynic’ or just being rhetorical? Just to be clear on your particular position.
And given this past national election’s increase black voters voting conservative maybe you’re you’re describing more inner city voters?
In general, I think it is a great political idea for groups to vote in different directions. If everyone in Northern Ky, as an example, always votes for Party X, eventually, Party Y quits caring what Northern Ky thinks, because they are never going to get their votes anyway, and Party X only pays lip service, because they know they are going to receive all the votes in Northern Ky anyway. You are seeing this nationally with the Latino voting bloc, neither party can count on a solid vote either way, and the Latino population has all sorts of issues that vary by region, so they are going to have to be courted to get their votes, which is entirely proper.
As to you question, probably more inner city voters, which are predominantly black. Lets put it this way, when you hear white Republicans loudly proclaim "everyone knows what goes on in Philadelphia", and decries the "rampant fraud and cheating" in "Democrat run cities", like Washington DC, Chicago, Milwaukee, Detroit, Atlanta, etc. Do you really think the underlying message is not racist? I don't think you have to be Jesse Jackson or Al Sharpton to figure that out.
