Aside from your efforts to simply slam the South. I have mentioned on this forum a number of times that here in Nashville that the midwestern transplants tend to be more fiscally conservative than the local old timey Dems. The La La Landers we get here from Kalifornia are nearly all semi-Commies and at the vanguard of my enemies in the culture war..
Now let's take My evil homestate of Mississippi, there has hardly been any Yankee (other than black Yankees returning home) migration yet Republicans win nearly all state wide elections and have since the mid 70s after the old Dems ..Eastland and Stennis moved on. I suppose that too is because of racism...nothing to do with ideology aside from race. Race is a factor...it's factor everywhere but there are other issues as well...culture and taxation for instance.
BTw, I don't think Gingrich is a funny name. He was a decent leader but his personal life left him wide open to our enemies in the media.
Your attempt to deny that blacks in the South are largely responsible for Dems getting elcted these days due to their high population numbers is simply wishful thinking. The Deep South is the heaviest concentration of blacks in this country as a percentage of total population and they vote overwhlemingly Dem. They also control nearly all metro governments in the Deep South and their policies have had their effect.
I don't know much about Boston, but let's again be honest. The schools in Boston were not segregated the way schools in the South were. No black kids were denied admission to a school in his neighborhood because of his race. That is exactly what happened in most of Dixie. Those kids in Little Rock in the 50s lived a few blocks from the school but were denied admission because of their race. That did not happen in any northern city that I am aware of. Boston's neighborhoods like many northern cities, where highly ethnic and 'self-segregated'. The neighborhood schools reflected those housing patterns. The 'fights' in Boston were when a Federal judge decided to bus kids past their neighborhood school across town to enforce an artificial racial quota plan. It had nothing to do with unequal access to education. The same thing happened in most Northern cities even in cities like Pittsburgh where there was no such thing as an all-white or all black school. You went to the school in your district --- no exceptions!
Federal judges (LBJ and Carter appointees) suddenly decided that every school should reflect the racial percentages of the entire district and neighborhood schools were destroyed while millions were wasted on transportation that could have gone to education. What were once outstanding public schools for all children, black and white, have been turned into nothing but toys for Federal judges. But what got that ugly ball rolling was Southern governments passing laws that denied government services to people because of race. You can't wrap yourself in the constitution with one hand while defending southern governments who were violating the very spirit of that constitution with the other.
