Reading this write-up after having read Nate Silver's post[1] today on how the Republican party has a harder time getting Silicon Valley talent leads to an interesting thought. Going forward the party that can successfully target the younger, smarter base will have a SUBSTANTIAL advantage in developing better systems. Assuming there is not some ceiling on how much better technology can impact efficiency, these systems will translate to exponentially more effective platforms for the party with the brightest youth.
You could also argue that Republicans will slowly peel off disaffected or disenfranchised talent as technology in politics becomes less of a cottage industry for seasonal fruit pickers and they have the lawyers to push against the true ceiling you're talking about... the legal hurdles and the stagnation of innovation that comes with winning and scaling.
