Apparently, as part of their strategic plan, Princeton will start accepting transfers in 2018, at the earliest but the OP may not be what they had in mind:

I also think Penn would be the best choice. You don’t have to be in DC all the time. Penn has a vibrant intellectual community and offers a lot of opportunities to the political science student. The lower COA makes the deal irresistible.
Thanks to all replying. In response to those bashing me about Harvard and Princeton, they were my top choice schools (and the ones my parents were pushing me towards) and I dedicated most of my time and effort to getting into them, but I always had Penn in the back of my mind because I wanted a strong poli-sci mixed with a strong understanding in business/economics to get an economy-focused education to politics. I am finally getting over the mourning period for Harv. and Princeton and am now clearing my mind to the options I have in front of me. All of you have been so helpful with giving me logical and rational reasons to make the best decision. @PennCAS2014 thanks so much for your advice and I will certainly PM you with questions and anything I have in mind concerning Penn, right now I am heavily leaning towards it and now that I am looking more, in-depth and researching the benefits of Penn I see it has so many opportunities to offer.
For all: I would appreciate if others with different opinions would continue to comment and help my brain grasp the amazing and different opportunities/choices I have ahead of me in my life
@Jman1177 glad i could be helpful. Please do reach out with questions- i’m happy to answer them
