People need symbols for some reason (that's why religion, government and art are full of them). The idea of Yahweh being our only king, and his law being our only law is hard for people to accept because it is not tangible (cf. 1 Sam. ch. 8). A president is a tangible symbol of protection. Because of this power, even people who don't worship office holders are forced to interact socially/politically with those who do. That means that POTUS is the most important position to statists, and a also to strategy-minded liberty folk.

In 1913 the Dark State weasled in the 'Federal' Reserve and the IRS. The Fed has slowly but successfully depleted the value of our dollar. Where one income used to supply a family, at least two are now needed. And the PAPERWORK and DOCUMENTATION to satisfy the IRS is absolutely mind numbing and time consuming. And if you try to open a side business.. the paper trail treadmill just gets worse. Have kids to raise under this reign of terror?.. the treadmill just got much faster. Takes time and more money.. because the 'Fed' continues to increase the price of things so.. and as you look at the taxes they take out of your 'income'.. well, you better keep trying to climb that corporate ladder.. whoops more time at the corporation.. hardly any left to see your family?

This burning of each family's candle at both ends by these evil twins(one devalues/the other takes what's left) is creating a treadmill that gets harder and harder to stay on. Time for Involvement with government / being a 'watchful citizen?' .. has turned into vote, 'make a wish for the best' and run. 

My answer is the treadmill that Americans allow to continue.. it's the evil twins.
