It's a decent argument but wouldn't Dems have always had this advantage? Obama had big support among college educated voters, Gore/Kerry had an "intellectual" base against "low IQ" Republicans, and I doubt anyone ever wanted to work for Dole's DOA campaign. I think this is one of those things that's less of an advantage but more of a small detail that is baked in the cake already.
Yeah this is a fair point, but I wonder if it’s gotten worse. This isn’t quite analogous but in the past few years a lot of Republican rising stars with seemingly bright futures have basically left politics because they don’t like putting up with it (I.e. Gallagher, Paul Ryan, ect).
I could see a similar thing going on in the machine where many of the GOPs historically best strategists, researchers, and campaign managers just no longer want to put up with Trump all the time and have left.
