More than half of voters say they have heard enough from Sarah Palin and would rather she not wade into political debates in her outspoken manner, according to a new NBC News/Wall Street Journal/Annenberg poll

Fifty-four percent fall into that category. That includes a sizable chunk of Palin's Republican Party — nearly four in 10. A majority of Democrats and independents say they prefer to hear less from Palin.

"I hate to think that the Republican Party is going to be leaving me. I don't want to leave it. But if it leaves me and it keeps straying toward that liberal, failed agenda that the left, that Barack Obama just exudes, then yeah, I'm not going to hesitate" to leave, Palin said Tuesday on Fox News.

Palin holds no elected office nor is she a candidate, but the former Alaska governor and 2008 vice presidential nominee has campaigned for congressional candidates this cycle and regularly opines on big debates on her Facebook page. This week, she called for the impeachment of President Obama.

The poll shows that 32 percent say they've also heard enough from former president Bill Clinton.

The survey was conducted from June 30 to July 7.
