The results of a new poll shows there is more potential backlash against the Democrats in charge of Washington in this election year. This time, it's independent voters who are angry.

The Associated Press - GfK poll found that 58 percent of independents and 60 percent of Republicans say politics is making them angry. Only 31 percent of Democrats who were polled said the same.

About 7 in 10 independents and Republicans were disgusted, compared with 4 in 10 Democrats. And independents and Republicans were more likely than Democrats to be disappointed, depressed and frustrated.

"There's a yellow light flashing" for Democrats in the numbers, said Ann Crigler, a political science professor at the University of Southern California who has studied the relationship between voter behavior and emotions.

Some political analysts believe in order to win elections, you must win over independent voters.

Only about a third of independents polled say the country is moving in the right direction, and more than half say President Obama is doing a poor job as president.

"I'm not happy with Republicans," said Ed Perry, 66, an independent from Lowell, Ohio, who thinks government is too large and expressed anger in the poll. "But I'm really unhappy with Democrats."
