You left out a little detail there
Those Southern Democrats are now Reagan Republicans. They are still into election fraud of every sort, but it's in the other direction now.
Pointless to argue with a neo-GOP fool, but it is also important to distinguish between voter fraud and election fraud. The number of individuals who commit fraudulent acts in order to vote has always been miniscule, on the order of ones. My recollection is that all of Rove's determined efforts resulted in six actual convictions for voter fraud. That hasn't stopped voter fraud from becoming the banner cry of the haters of democracy as they work to disenfranchise as many 'hostile' voters as possible.
Election fraud is quite different. That's a large-scale and organized project that actually changes the results of elections. Historically, two of the worst abusers were Democrats, both dead and one convicted and disgraced. Nowadays the overwhelming preponderance of the evidence points at organized election fraud by the neo-GOP.
Sadly, I don't election fraud is the largest problem. I'm hanging between gerrymandering and corporate personhood AKA Citizens United. Gerrymandering has a long tradition of precounting votes, so perhaps it wins. The large numbers of eligible voters who don't bother are sadly correct that their votes don't matter, because the districts were deliberately and scientifically drawn to predetermine the outcomes.
