Anger: It's the defining political emotion of this campaign season. It's boiling across the country, much of it directed at President Obama and the congressional Democrats over the way they have handled the economy. Not far behind is dissatisfaction.

The combination, detected in a new ABC News/Yahoo! News poll, spells trouble for Democrats three weeks out from the election. Angry people, analysts say, go out and vote. Dissatisfied people tend to stay home.

With the recovery stalling, unemployment stuck at 9.6 percent and the housing crisis entering a dangerous new phase as bungled paperwork and outright fraud force a halt to foreclosures across the country, there's plenty to get upset about.

The poll, a national, random-sample survey conducted by Langer Research Associates, shows just how deep the anger runs: A sky-high 25 percent of Americans say they are angry about the state of the economy — many more of them Republicans than Democrats, a key reason why the economy's woes appear to be playing to the GOP's favor.

Dissatisfaction, which thus far has grabbed few headlines, runs sharply through an even larger swath of the electorate, but it holds just as much peril for the Democrats struggling to hold onto control of Congress and many statewide offices. Fully another 60 percent of Americans say they are dissatisfied with the economy — and many of them are Democrats.

So just who is angry? And who is dissatisfied? And where are they?

The short answer: pretty much everyone and everywhere. The real story underlying this election may be how uniform and broadly felt the unhappiness is.
