Trump, good schools, incredibly successful businessman
Fiorina, fired for destroying HP
Carson, a retired doctor
Paul, daddy's wanna be. A doctor turned politician that loves to plagiarize.
Walker, a college drop out and successful governor
Trump and Walker are the only ones that warrant further look. Walker, though, fails because of his support for illegal amnesty. Only Trump is clear about building a fence and deporting illegals.
I notice you left out Princeton Grad/Harvard Grad Cruz.
