What I think (hope!) you’re missing is that a great portion of the voting public feels that neither party represents their values and principles. If we could take the Republican Party and make it into a robust conservative voice, I think you’d see a response from the public that would surprise you. At least I hope we’re not past the point of no return.
You’d wind up with the same people demanding the same things and you’d be back to square one before you knew what happened.
