If she gets the nomination she will win. Obamas minister problem will be seen as the reason he lost it and will be blamed on the Hannitys and Limbaughs. You can take that to the bank. There is a much better chance Clintons supporters will sit home or vote McCain than the other way around.
If McCain wins the Republican Party will go Liberal/Progressive. If he loses, the Republican Party gets a big message.
If Hillary wins and implements half of what she wishes it will shock America, maybe to the point where they have had enough of modern liberal/progressivism.
Of course, either could take down the country with all the libs in the house/senate and packing the supreme court, but I would rather have it blamed where it belongs than on the Grand Old Party.
