They actually believe they are more intelligent (on any given subject) than conservatives.

Yep and I'll give you an example of some libtards that I went to college with, studied the same degree program with, graduated with, and years later when I finally stopped interacting with them they were clearly quite bitter than a "dumb conservative" like me was being way more successful in life than them in the same amount of time and with essentially the same starting conditions. They were still living at home while in just five years after graduating with them I had paid off my student loans, paid off a "new" car (a lightly used Lexus that I still drive over a decade later), and had bought a house.
