At this point, I think this may be a mistake.
A Hillary nomination is more centrist and appeals to more independents than an Obama nomination. She is much more dangerous as a winner with a Democrat Congress.
An Obama nomination leaves her out in the cold where she will NOT tolerate being. She will work to get him beaten so she can try again in 2012. A force of McCain, independents and the Clintons can likely beat Obama.
The reverse is not true. Obama would not work to defeat her because he has far more time to try again.
She is going to win Pennsylvania and continue, but Indiana and North Carolina would be good places to stop her. She can rest firmly assured of the nomination in 2012 if Obama is beaten by McCain.
Hitlery will be too old in ‘12.
