Looks to me that it is a delusion to think we can do anything at the polls to stop government growth. The Republicans want more government, and so do the Democrats; they only argue over over which sectors to make grow the fastest.
It also looks like the exponential growth in the cost to acquire energy will change our history of economic growth into a future of economic contraction, and you can be sure that when massive numbers of people are facing ruin and starvation in an ever decreasing economy, no existing government will likely survive.
As soon as we blow through the last of the conventional oil discoveries, and must rely increasingly on the super costly tight oil, offshore oil, and tar sands oil, the economic contraction should accelerate. That won't take anywhere near 20 years, so I think an adequate jury pool will be the least of our worries.
The only real question in my mind is how the end of most of the governments around the world will play out. Will the politicians and power brokers peacefully close up shop and run for nearest country that will protect them, or will they hunker down in protective bunkers to command the few soldiers remaining loyal to their rule in a fruitless effort to stay in power?
There are ways to cushion the change in economic circumstances for ordinary citizens, but none of those will be adopted by the ruling class since that would require them to stop their plunder and control and to quit taking the lions share of the dwindling economic pie.
"Bend over and grab your ankles" should be etched in stone at the entrance to every government building and every government office.
