Unless the Repubs can come up with some kind of epic shift in ideological dogma, I really don't think they can win presidential elections without their increased use of selling lies, fear and hate as their prime motivator/election winner.
I mean, when was the last time the Repubs came up with any kind of ideas that favored the uplifting of all boats for creating/sustaining a healthy and stable economy for everyone? Last I heard it was Ronnie's trickle down scam for, of and by the very rich that Ronnie dearly wanted to suck up to and identify with. It seems like he totally over-reacted in his desire to erase any remnant history of his days being in union leadership. Presently, it's the same old tired song and dance of smaller gov't (that gives the few with huge influence even more power), personal responsibility, deregulating the banksters and investment scam artists, getting rid of any kind of federal assistance programs for the needy and advocating for anything else that cripples the middle class and the poor to give the rich and powerful ever more riches and power.
With national demographics shifting away from those classic Repub ideologue talking points, and with the middle class and the poor increasingly realizing how they have been denied the chance to enhance their quality of life and live the American dream so that the very rich can acquire even more control of the nation, having the Repub Party being recognized as the defenders and enablers of these power grabbers is not going to play well in the near and distant future.
Jeb Bush represents precisely that kind of image, and although Hillary is a recognized big business advocate, her Dem Party pedigree demands that at the least she favors legislation that includes having the middle class and the poor being able to have a strong voice in government and a better chance at living the American dream for themselves and their children.
