It's black people.
Seriously! Slavery is America's original sin. It's not a coincidence that the red states are the Confederate ones. It's not accidental that people didn't start trying to cut funding for public schools until desegregation. It isn't happenstance that the libertarian heroes on the right keep being associated with white supremacists, or that the GOP has adopted the tactics of John Calhoun. And it certainly shouldn't be surprising that this all came to a head when a black President took office. The racism that was built into the founding of America has been slowly burning out since the Civil War. This is just another skirmish.
While black people are a huge part of it. In general I feel that its the death of "White America". America is changing now.
NPR actually did a slice of life-like reporting on it. The days of America of being a nation filled with white Europeans who all consist of a heritage of apple pie, baseball, and Elvis has nearly faded away. Hell even the late Boomers and early Generation X's America of mostly white Europeans with blacks and Mexicans as only small visible minorities that "you can ignore" is pretty much starting to choke. America is increasingly becoming a more and more diverse nation with Asians (especially), Arabs, other Hispanics, and Africa moving to a community near you. This also ignores the fact that even the "traditional" minorities Mexicans and African-Americans are further integrating with everyone else. Hell America society in general is integrating at a rapid place. Minorities are no longer as interested as staying in the city so you can no longer be "safe" from them. They are moving to the suburbs
with many moving to integrated communities.
This is what the Republican Party is all about. The last "hurrah" of
White "Traditional" America. A large segment of Americans are uneased that they are starting to see *gasp* BLACK teenage boys in their community. And....some of them....don't dress WHITE!
And their daughter is dating a....a....LATINO! Why is everything so terrible now? Why can't the
White Old America come back? To be fair though not all white people in suburban areas think like this (obviously). But the real hivemind comes from the areas that are not diverseful. They see their nation changing from the outside. The cities are full of
blacks and hispanics "dangerous people", more and more minorities are coming in ruining American culture, and now there's a black president who clearly can't "relate" to the average American. Neverfear!
The Republican Party is here! Here to save America and bring back its culture and tradition! Fighting for the
white common man!
This is what propelled the party to the top. Unfortunately this is also going to be its downfall. You see the first problem is that with all these minorities moving in and growing, they aren't going to be happy, let alone identify, with a party that demonizes them. As they become more of a percentage of the population, they have more political power as the share of votes for your party decreases and your rival that
gives them free money is friendly toward them gets more votes. There is also the fact that children who were born during this integration grow up and are now used to an America that is diverse. They are used to seeing non-white kids in their schools, used to seeing a black president. So they are less hostile to these things and see the Republican Party as old, traditional, and even racist. This will be the Republicans downfall.
