These are pointless counterfactuals because Jeb! could not be elected to begin with.
There is no popular electoral majority for the Republicans' plutocratic economic policies. The only way they can win with that platform is to cover it with a thick layer of racism and culture war grievance-mongering.
I think there are plenty of examples of the GOP winning elections in the past running on (what Democrats allege are) "plutocratic economic policies" while not being anymore "racist" than the Democratic nominee. So, even if that is how they are getting a majority NOW, I don't think that is the only formula to win with right-of-center economic goals...
