It was Jock Scott, a former Democrat state legislator who ran for Congress in 1985. I don't recall if he ran as a Democrat or Republican that year. His late father, Nauman S. Scott, was a Republican who lost a race for local office in 1966. Nixon made him a federal judge; Scott was unpopular among conservatives, the epitome of the "big government" judge. By the middle or late 80s, Scott had also become Republicans. It was Jock Scott and now Alexandria Mayor Edward "Ned" Randoloph, then a state senator, who organized Rapides Parish for the Carter-Mondale forces.
So is Jock Scott a RINO or is he simply a conservative who was a Democrat back in the old days because that was the way to succeed in Louisiana politics (not to mention that the Democrats weren't as liberal back then)? I'm not too worried about him having organized for Carter in 1976, since most white Southerners were for the Georgia governor back then; Carter actually won every Southern state except for Virginia and Oklahoma.
