What Republican candidate DOES have a chance? Each Republican candidate is against women's health, immigration reform, and wants to put boots on the ground in the middle east. Their policies are not very easy to overcome in a general election.
I think there are Republicans that CAN win (certainly not Trump) though I, personally think Hillary is the next President. I dont claim to be a political expert but if I'm a Republican, my strategy is to not ruffle any feathers of the poor in hopes they dont care enough to come out to vote against me. Just sit tight, dont say anything stupid, hope the poor dont vote, and hope to win a good number of middle class votes which is possible. Trump, however, is pretty much the opposite of this as everybody and their brother will register to vote against him.
