"Because an Obama-friendly moderate stands absolutely no chance of winning a Republican presidential nomination anytime soon. The coalition that would nominate such a man (or woman!) exists, sure. In the Democratic party. Not the GOP."The Republican Party has no interest in ever moderating itself - 2016 or any time in the future. It will take several presidential elections before it even considers something o drastic. We're talking 16-years minimum.
Today TPM and WaPo both dissect a new Gallup on the ever shrinking GOP. Other than church-going Caucasians, every other demographic has left them.
By 2042 the United States will be "majority-minority," when ethnic/racial minorities will make up the majority of the population. Currently 10% of American counties are "majority-minority" and another 7% are reaching that point.
Good luck in your purification attempts, GOP. You'll be joining the Whigs soon enough.
