timeline 191 WI: Huey Long isn't assassinated

In timeline 191, sometime after the Richmond Olympics in 1936, Jake Featherston had ordered the assassination of Huey Long of Louisiana. Reason being Long was a radical Liberal, and had been Cordell Hull's running mate in 1933. What if Long had either survived the attempt, or had learned of the conspiracy, and stopped it?

Could he have caused trouble for Featherston later on? Could he start a civil war in the Confederacy, maybe even overthrow Featherston? What do you think?
