What exactly will Republicans run on?

[The Free North]

This is why i don't think Hillary is the best candidate for this situation.

Unless the economy collapses this year or early next year, Republicans will be deprived of their best talking point (we know how to make jobs, etc). There is nothing pressing in terms of foreign policy to run on and considering how close Obama and Bush look now, the main challenge would be from the left, but only Paul will do that. Obamacare will be there, but in 2 more years, who knows what its approval ratings will be. Anything else is really just minor (social issues, environment, energy, etc).

So with nothing to run on, the republican who wins the nomination will go after Hillary as an elitist, untrustworthy insider and there is 2 decades worth of baggage to draw on in that regard, so they may not even have to run on policy, they can just beat up Hillary and it may work if enough people are convinced by it.
