Palin was the only one who broke 50 percent on the Wall Street Journal/NBC News/Annenberg poll, with 52 percent of respondents saying she should "be quiet." Since resigning as governor of Alaska in 2009, months after she ran for vice president as the Republican candidate, Palin has appeared on television talk shows and even had her own reality show.
Civil rights leader Jesse Jackson came in second at 45 percent, followed by former Vice President Dick Cheney at 42 percent and former House Speaker Newt Gingrich, R-Ga., at 39 percent. The Democrats did a bit better with 37 percent wanting to hear less from former Vice President Al Gore and only 31 percent saying the same of Bill Clinton.
The Journal described Jackson's number as a "bit of a mystery." Jackson has faded from the headlines in recent years, appearing in the news mostly because of the legal troubles of his son, former Rep. Jesse Jackson Jr., D-Ill.
Jackson did worse with those over 50 with more than half saying he should pipe down and only 35 percent of those under 35 agreeing.
Twelve percent of those surveyed said all six should continue to say whatever they want.
This week, Palin called for President Obama's impeachment in a piece this week on the conservative website Breitbart.com. She attacked his immigration policy and compared him to an abusive husband.
The poll was conducted between June 30 and July 7 with a break on July 4, and 1,392 people were interviewed. The margin of error is 3.14 percentage points.
