I am happy to read that New Horizons has a nuclear power battery: http://en.wikipedia.org/wiki/New_Horizons#Power
Ok, hard to go without one in that kind of mission, but when I read this:

Less than the original design goal was produced, due to delays at the United States Department of Energy, including security activities, which held up production.

I am sure the uneducated mobocracy tried its best to throw a monkey wrench into the works.
