It appears all of the Mainstream Media has now picked up the MSNBC technique of turning everything into racism. Ryan isn't "blaming" minorities here. Conservatives in general are surprised that segments of the economy hardest hit by President Obama's policies turned out as enthusiastically as they did for him this time. Yes, there are rural areas that went Obama, but it shouldn't really be a surprise that urban areas were his strongholds.
Ryan was caught by surprise by the same phenomenon a lot of conservatives were; Obama's failed policies hit his base harder than anybody else yet they had his back. That's just reality. Media Trackers has more on this.
