Mine wasn't a blanket statement regarding the USA electorate, mine was a precise reference to "Georgetowners were predictably appalled by the onslaught of the rubes and the rabble." And yes, I was going on the assumption that those Georgetowners didn't attend those rallies anymore than I did. We saw the rubes and the rabble on TV and read/watched the interviews in print or as video on the Net or TV.
BTW "rube" is a gender neutral expression, here is what Merriam's says: Definition of rube. 1 : an awkward unsophisticated person : rustic. 2 : a naive or inexperienced person.
It expresses gently and concisely the tenor of all the other dictionaries. As I've mentioned before, but it bears repeating, in German there is a popular saying "Those who can read have a clear advantage" to which I usually like to add "and those who comprehend are the real winners". ;)
