I think national issues play into gubernatorial races less than, obviously, in Senate and Congressional races. Much less.

If I were president, I am not sure that I would offer Ed Rendell the job of chief of staff.

Creating new jobs for Pennsylvanians continues to be my highest priority throughout the Commonwealth.

I think for a certain demographic of American families that are not living below the poverty line, what is now becoming the working poor, I think they realize that their young daughters - and their sons, quite frankly - need to learn a skill set that is going to never go away, and I think that they see that in technology.

I always urge women to aim for the highest job they can get because you get more money and you get more support and you get more control, and those are the three things that actually make life easier.
