The people in the Southern "Jim Crow" States were not Conservative Republicans. They were racist fascist Democrats. They were not in support of the Constitution. These were people like Senator Al Gore Sr. Senator William Fulbright, Senator Robert Byrd etc.
We conservatives support, honor and defend the Constitution of the United States, particularly the restrictions it puts on the power of the Federal Government. Just because some radical Democrats tried to hide behind the exclusionary clause to excuse their abhorrent behavior and hatred doesn't make defending the Constitution a bad thing. Remember it was Republican President Eisenhower who sent the 101st Airborne to Arkansas to enforce the Constitution. I am old enough to remember. Ike was a "Con".

EDIT- you are confusing the term "Right" as it applies to American politics. The Southern Racist Democrats were not to the Right of the Northern Republicans. The terms Left and Right in America are different than in Europe.
Here the model is a long line with Moderate in the center. Moving Left you find Liberal/Progressive then Socialist then Totalitarian. Starting in the center and moving Right you find Conservative then Libertarian then Anarchy. For Southern Democrats to be to the Right of Conservatives, they would have to be for even more individual rights and Liberty not less. To be quite honest, if they were anything it would be akin to Fascists. Fascism is another form of Totalitarianism and that, too, is on the Left not the Right in America.
It is in European politics that Socialism is on the Left and Fascism is on the Right. But their model is very different. That political model is more like a pair of railroad tracks heading in one direction with Socialism as the Left rail and Fascism as the Right rail. But both have Totalitarianism as the destination. This is due to the legacy of monarchy in Europe. We have no such legacy.

EDIT- Man are you misinformed about Ike. The Interstate Highway system was built for National Defense! Ike realized the importance of being able to move men and material from coast to coast and border to border in the event of war and there wasn't any way to do that in America. We had only "routes" mapped out that ran through small towns, single lane roads, over weak bridges etc. The issue was National Defense. That is why all the even numbered interstates run East and West and the odd numbered interstates run North and South. A military convoy or individual vehicles would always know which road to take based on the direction they wanted to go. They were also built with long, unobstructed straight sections every so many miles to serve as makeshift runways for military aircraft.
He didn't make the tax rate 91%. It was 91% but loaded with all manner of loopholes so no one actually paid that. It was that way before Ike got there. He and most Americans supported Unions back then. That was when they were still needed, before there were all manner of laws protecting employees and controlling working conditions. As far as his warning about the undue influence on scientific research and education by the Military Industrial Complex he was right about the undue influence of Federal research dollars only it turns out it wasn't the MIC but rather, Liberal Environmental Fascism that ended up doing that. Watch his farewell speech below, but instead of Military Industrial Complex, substitute the words "Environmental Activism" and he is right on the money. He got the threat right but from it came from a movement that didn't exist yet.
