You also have to realize these are indoctrinated young people through textbooks teaching them America is racist horrible etc. Obama was positioned as a uniter /centrist (morons believed this?) and voting for him would rid our nation of its collective guilt.
Young people are ignorant through lack of life experience. They are easy targets for Democrats and Dems go after them. Young white people are taught to be ashamed of their race and history. Voting for Obama was sold as the cool thing to do.
Now... hopefully they are waking up. Universities though are where the young are radicalized. Listen to the interview with Obama’s communist college buddy. Becoming a professor (though Obama was never more than an instructor) and ‘community activist’ were acceptable paths for socialists.
Gullible and need to be motivated would fit many
