WE have no doubt that had the South won its Independence, that Robert E. Lee would have surely been elected as the second President of the Confedertae States of America, assuming that he would have been willing to run and all.
Now IF, after the south lost, and during the aftermath, had Lee's United States citizenship been restored, could Lee have obtained political office? Again, we are assuming that Lee would have been willing here to except such a calling. Which I don't thing he would have, but for the sake of discussion here we are saying that he would have done so.
It would be a sure thing that Lee would have easily been elected as a Governor, or even U.S. Senator from Virginia. And as Senator, he would have lead the Southern Congressional delegation in both houses of Congress. Question: Would his charactor and name recongition and political power at that point, have been enough that, had he lived, he could have been elected President of the United States during the 1870's?
Historically we must remember that Lee was well thought of not just in the South alone, but had quite a following from those in the North also.
