Why don't you mention the influx of "damnyankee" Republicans moving into the South with funny names like Gingrich? The old Southern Democrat congress-critters-for-life got all the big defence and space projects located in their states, but along with those pork-dollars came a lot of soldiers, saliors, and engineers and such from the North who would vote Republican.
It's true that a few Southern states voted for Goldwater in 1964, but let's be honest about why. It was only because of his opposition to the Civil Rights Act, not because he was a small government conservative. They still wanted pork, they just didn't want to eat it at the same table as blacks.
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.
