Sometimes the media will also blame the earlier leader, if it fits their agenda, like this http://www.gopbriefingroom.com/index.php/topic,221672.msg1026261.html#msg1026261
We saw that with the whole Bush's Fault meme, too. It was the Community Reinvestment Act policies against 'redlining' (another word for prudent release of capital in the loan market) which led to the insane real estate bubble, and a host of financial 'products' designed to comply with the law and avoid lawsuits, but which actually set up the whole disaster in 2007/8 along with the derivatives market.
Clinton's Fault, and those kick the can down the road policies which don't go into effect until someone else is in office are designed to transfer blame to the next office holder. I honestly think the whole Obamarama was supposed to be a one term show, so the Obamacare went into full effect under a Republican President and GOP controlled Congress and they got the blame.
There is always a way to blame someone else if you have a willing press and stupid people.
I agree, education remains key in all this, but with Honey booboos and lardashians, and 'murica's got talent, getting past the twitter feeds and Facebook fence (where the gossips hang out) is going to be tough.
