because many of them are filled with leftism and are noobs at politics hence why a clown can get elected. Also they prefer someone who seem to be good looking and friendly than someone realistic and too pragmatic. Don't worry if Obama gets elected I am pretty sure that he will fear for his life every day. I don't think everyone likes Obama, people living from the ghetto, people with a low income, students and perhaps hispanics as well as students and people who work in liberal profession like him not the others.
In general, the less the people are educated, the more they tend to vote democrat. Don't jump on me people because I expressed my opinion.
I dont think the people that vote republican are any smarter or have the perfect angle on politics. I read allot about current affairs and politics, I dont share your views.
Shame in this day, someone would bring up a fear for his life. I guess that is the sad state of thoughts by some Americans.
Actually Obama leads with voters with a college education. They groups you mentioned have not been his strength.
