It may explain where much of the frustration is coming from, and it isn't about the generic "blaming Congress". The generic "blaming Congress" IS the problem.

When he wants to be, the president is a brilliant and moving speaker, but his stories virtually always lack one element: the villain who caused the problem, who is always left out, described in impersonal terms, or described in passive voice, as if the cause of others’ misery has no agency and hence no culpability
And this excerpt gives concrete examples of "vague ideology"
To the average American, who was still staring into the abyss, the half-stimulus did nothing but prove that Ronald Reagan was right, that government is the problem. In fact, the average American had no idea what Democrats were trying to accomplish by deficit spending because no one bothered to explain it to them with the repetition and evocative imagery that our brains require to make an idea, particularly a paradoxical one, “stick.”
Nor did anyone explain what health care reform was supposed to accomplish (other than the unbelievable and even more uninspiring claim that it would “bend the cost curve”), or why “credit card reform” had led to an increase in the interest rates they were already struggling to pay.
Nor did anyone explain why saving the banks was such a priority, when saving the homes the banks were foreclosing didn’t seem to be.
All Americans knew, and all they know today, is that they’re still unemployed, they’re still worried about how they’re going to pay their bills at the end of the month and their kids still can’t get a job. And now the Republicans are chipping away at unemployment insurance, and the president is making his usual impotent verbal exhortations after bargaining it away.
This is why he is failing. People need to hear what the problem is, who caused it, why they did what they did, why they were wrong, and what our plan is to rectify the situation. Vague ideologies about "them" and "Washington" does not explain any of this and therefore, people have nothing to vote for (only things to vote against). See: 2010, November
