That's a giant leap to make -- the conclusion that she "struggled." Let me tell you I went to a lot of colleges in a short time and it wasn't because I struggled. It had a lot more to do with restlessness and doubt over whether I was following the right path.
The notion that those who drop out or come and go from college are somehow unable to learn or aren't as smart as others is an elitist attitude. Some people just don't fit in the world of academia, and frankly some of the best conservative leaders I have met fit this description. For the most part I find they are among the smartest and best informed of people I meet.
A prime example of this would be Rush H. Limbaugh!!!
