Chris Christie wins it. I'll guarantee that right now (unless he has a MAJOR blooper).
Most Americans aren't far left or far right. People tend to be moderates at heart. The left has been winning because the right keeps getting more and more crazy right. Christie and other Republicans that win elections in blue states are proof that you can be a smart Republican and don't have to listen/watch Fox News to get your talking points.
Now Clinton does have a glimpse of hope here. She was the original person that stated we need to fight outsourcing and keep manufacturing jobs in the USA which Obama copied and Republicans voted down. If she uses that as her primary focus, she may win.
Republicans use to be proud of American made, until Obama took a stand on the topic. I believe everyone is sick of the old factory workers being on welfare now. If we bring back the low skill jobs, we will have less welfare payout. Most jobs outsourced are low skill and most people on welfare are low skill workers. There are only "so many" jobs at McDonalds.
