Sure, Duncan Hunter wins the GOP primary and is the GOP nominee and he will take care of the rest. Name recognition solved as people want to see who this nominee is who beat the odds and he’s more than competent in interviews, debates, speeches, personal appeal and with his Vietnam vet status and his son’s Iraq/Afghanistan service he will do just fine in a general election and, frankly, he would keep the ‘red’ states and with his trade status would make his mark with many ‘blue’ staters. And he’s not an easy man to mock.
Have to have a plan to get there. Which his campaign doesn't have. Good intentions or dreaming it will happen, doesn't make happen.
