The entire thing - left-right, Dem-Rep, red-blue, apathy and ignorance - is as Taibbi states...its the circuses end of the proverbial bread and circuses:
"… Already long ago, from when we sold our vote to no man, the People have abdicated our duties; for the People who once upon a time handed out military command, high civil office, legions — everything, now restrains itself and anxiously hopes for just two things: bread and circuses."Juvenal, Satire 10.77–81

Its all devolved into spectator sport...and MANY of the go-along, get-along "centrists" at DU, and other progressive sites, and organizations and especially the sell-out Democratic Party are guilty of living a lie. The lie is that they are self-identified "liberals" only in the sense that they are fans of them more so than the "other side". Its like people who watch the Super Bowl every year because its an "event", but they have no actual knowledge of the teams playing - no real rooting interest, just a popularity contest.
The "fans" of each side probably make up about 40-50% of their respective totals. Think about it...right after the 2008 elections, self-identified "Republicans" was down to about 20% of overall voters...no one likes a loser! When the Tea Party was ginned up by right wingers and generated an external enemy for the sheeple, well, we've all seen the videos, heard the clips and are living in the aftermath...
