You wanna know what hackery is Jack. Its people who express the nonsense that you just did. Than and your denial of reality. In your blind desire to attack the Democrats you ignore the fact that the slide began with 2 republicans and then continued with the democrats. In point of fact, the problem is economic and racial and politicians of both stripes contributed to it, messed it up a bit, and sure did not help or reverse it.
But the worst sort of stupid hackery is the people who want to turn this into a hate the democratic party lynching when they conveniently ignore that 10% of the population was lost under two republican mayors and that was the BEGINNING of the slide.
So you just will NOT be allowed to have it both ways Jack. You will not.
