Most voters, (aside from those strict conservative ideologues) were probably also looking forward to 'changes' of some kind. I did not vote for Pres. Obama in 2008 or 2012, but I would have loved to see him deliver on his substantive campaign promises. Unfortunately, his tenure has not been exceptional. Yet it has served as an important lesson for my generation of Millenials: federal-level politics is largely a waste of time/money/interest. At best, federal (and many local) politicians are amebic, utterly spineless and moving in whatever direction the prevailing currents take them. At worst, they are unethical, corrupt, and deserve nothing more than our scorn.
The American political system is thoroughly--and probably irredeemably--corrupt. The sooner we accept this fact, the sooner we can devote our time/money/interest to finding genuine solutions to the many problems we face. We will probably never get rid of this political system--those who participate in it will not give up the opportunity to profit from it, and those hardcore partisans will continue to watch from the sidelines as cheer for their 'team'. The system, those in the red or blue camps, the media industry built around it, etc. will be like a headache in the back of our skulls that we must endure as we go about our lives. Just like the Baby Boomers who will form the overwhelming majorities there. Still, we will work around these inconveniences.
So in a way, Pres. Obama has done us a favor. He has demonstrated to us, conclusively, without any shadow of a doubt, that contributing to that system, directly or indirectly, is a waste of time. Thanks, Obama. I mean it!
