The entire left-right fight is total WWE.
They are over points that everyone cares about, but nothing will ever be done, no an actual solution will be discussed.
Other than that, they are the uni-party. War is good for business. Mo' gov' power is mo-betta.
Spend as much as possible, as fast as possible, as wastefully as possible. (thus, you can support more of your friends with more kickbacks. This also has to do with debt based fiat currency having to increase the amount every year.)
And, still many people see the corruption, but still vote for the lesser of the two evils.
