Of course, it's just not the Gracchi, it's the whole environment in which they lived. Just off the top of my head, a few similarities with the issues that would be dealt with up to and including Octavian:

1. Land reform and the problems of public land;
2. How to compensate veterans (colonies, etc.)
3. The entire structure of senate vs. assembly legislation;
4. The use of tribunes to force through legislation;
5. The question of having tribunes serve multiple terms;
6. The issues raised by Asian tax farming and plundering the provinces;
7. The rights or lack of rights of the rest of Italia;
8. And, of course, the ultimate issue - that when the Senate became threatened enough, radical tribunes were murdered. *shudder* Quelle precedent!
