Same could be said of anyone who wants to increase the size of our government.
The federal government is relatively small when compared to the enormous private sector government contracting industries that do most of the "work" of our government (outsourcing, in-sourcing). The gov't contractors, collectively, provide much of the campaign finance donations in an attempt (usually successful) to preserve the status quo.
If we really want large system change, we must understand the whole system, not just change the "ceremonial head" every 4 or 8 years. Our presidential election process gives us only a glimpse of the system (the system doesn't benefit from giving us a better look). To actually "see" and comprehend this whole system requires change in our own personal behavior including significant investments of our personal time. In a representative form of government, only a few of us will actually invest the time to understand; most will not. Sadly, most of us are too comfortable thinking that we've done our part by awakening every 4 years, shouting on blog sites like this, shaking our fists, and then going back to sleep for another 4 years.
If we really want change, we need to install a "change agent" from time to time...someone with the guts and independence to actually take action. No change agent will be perfect...good change agents will not necessarily be "nice" and some will even say ****.
