It will surely be canceled long before then, unfortunately. NASA and other science programs are a small part of the federal budget, but they have a large "single item" price associated with them that make them the first to go when Democrat administrations get in power who would prefer to transfer the money to social programs. Just take a look at how things disintegrated under Carter or how we abandoned high energy physics under Clinton (canceling the supercollider).
You could be right. The F1 engine that made the Saturn V possible started as a million plus pound engine project for the military; it made the trip to NASA when it deemed unnecessary (militarily) and was in development before JFK was nominated (the wikipedia sez the first full test was in March 1959). Also this (speaking of Demwits controlling both houses of Congress):
> http://en.wikipedia.org/wiki/F-1_(rocket_engine) — There was an uprating redevelopment of the F-1 undertaken by Rocketdyne during the 1960s which resulted in a new engine specification known as the F-1A. While outwardly very similar to the F-1, the F-1A was actually lighter yet significantly more powerful (9.1 MN compared to F-1’s 6.7 MN) and would have been used on future Saturn V vehicles in the post-Apollo era. However, the Saturn V production line was closed prior to the end of Project Apollo and no F-1A engine ever flew on a launch vehicle.

The U.S. House of Representatives decided in 1993 to halt the project after14 miles of tunneling were completed and two billion dollars spent. The laboratory, located South of Dallas, TX, is in the final shutdown phase.
