Even in the 1950s and 60s, the absolute biggest porkers in congress were the New Deal Southern Democrats. The supported every big government program that came down the pike, especially if the could get a piece of the action.
Southern Democrat committee chairmen really brought home the pork for their states. Bob Byrd was a survivor of that era.
FWIW, I may have been too cautious in my last post. In the three-way race of 1912 Wilson got 60, 70, 80, 90 percent in the Deep South states and 30 or 40 percent in the Northern states he carried. In 1916 he lost most of the North and carried all the South. Northern states had more people in those days, but it's entirely possible that a majority of Wilson's vote in 1912 came from Southerners. Of course many of the Northerners who voted against him were progressives themselves, but there were reasons why many considered the Virginia-born Wilson a Southern President.
