First off, Klein is being completely disingenuous about the changes within parties that have occurred since historical events compared to 2014. The parties of old with the elastic, persuadable massive white majorities are long gone. We have the majority of whites and minorities who have the stuff together vs. the non-whites and self-hating whites (Haters of Western Civ). Reactions to events, especially any event with a racial connotation, is going to have a tribal element to response. Klein, and his fellows in the media, have created this situation with the ever expanding culture war and never-ending immigration. Klein is also omitting that the Democrats of yesteryear were completely different because the New Left had not yet destroyed the Northern-Western GOP + Dixiecrat alliance in their quest to capture all presidential elections. Klein's Silent Generation and Baby Boomer forerunners destroyed the variability within the party with the New Left takeover and massive fundraising that made politicians representatives of the party's core interests over their specific regional interests.
Having read about Gamergate, it appears that someone was criticized for ethical problems, then they fell back on the sexist/racist/homophobic canard, and now it is a classic "we're the poor underdog despite going on Colbert and having the NY Times have our back" garbage while simultaneously acting in a shameless, goon fashion. There is a political reaction to this because Chick-Fil-A, Ezra, do you recall that? An executive made donations to an anti-gay marriage charity, and the puritanical outrage from the left was focused on a second tier fast food chain for a month. People are tired of the politicization of everything, especially when it is garbage, phony outrage from one of the left's pet groups. It is hard for me to take feminist outrage of misogyny in video games when I can find any degrading, misogynistic pornography I want on Google. Video games, chicken joints, this is all the left's making. They are the prime movers. They interrupt the norm to create a crisis. They are continuously attempting to sever ties that one tribe feels to its traditional ways in the name of progress, but in reality for political power.
Missing the bigger picture, look at election 2014. Normally, a midterm is a reflection of the public's attitude towards the president's performance and behavior. Clinton saw the GOP win in '94 while the Democrats improved in '98. Bush saw his party expand power in '02, while they were trounced in '06. Obama saw his party lose big in '10, and uhh, it does not look great for '14. This may surprise Ezra Klein, but he is most likely just not discussing it, but the Democrats are using tribal messaging for their get out the vote efforts. Steve Sailer has documented the shameless racial imagery in states with sizable black populations and the Michael Brown fiasco as ways for the Democrats to crank up turnout. The days of Jim Crow and slavery will return if you do not vote for Kay Hagan! Sailer is missing that in states without blacks, the Democrats are relying on the uterus approach with Senator Udall of Colorado going overboard with female genitalia focus, as well as tiny little Maine seeing appearances by Debbie Wasserman Schultz to speak of how anti-women Maine's system is as Maine for the last twenty years had two female US senators.
That is all the left has. Klein knows it, and possibly is concerned because with racial lockstep voting, who needs credentialed, Jewish pundits to persuade the ever shrinking elastic voter pool? All the media needs it agitprop sensationalists. The left is out of ideas. The right has few ideas, and honestly, freer markets is not going to get us out of our jam. The right can campaign on getting rid of Obamacare and fixing the economy, while the left campaigns on "Hate Whitey!" and "Vote with Your Vagina!" The culture war combined with population displacement has created these tribal political identities, and it will only get worse as time goes on. Eventually, enough people will see that the system is doomed and the serious questions will begin to be answered. At that time, no one is going to listen to the likes of Ezra Klein about a new system when he willfully lied about the state of the current dilapidated contraption.
