Americans' view of Sarah Palin is more unfavorable now than at any time since she was the Republican vice presidential nominee.

According to a poll released Friday, 52 percent now say they have an unfavorable view of the former Alaska governor, whose visibility remains high following her campaign efforts during the midterm election season. Her unfavorability rating hit 50 percent only one other time, in October 2009.

Those who view Palin positively have also declined this year, from a consistent 44 percent of the public in late 2009 to 40 percent this November.

She remains popular among a wide majority of Republicans (80 percent), as she was in November 2008 (83 percent). Among independents, however, she's fallen rapidly out of favor over the last few months: from 43 percent approval in July to a record low of 35 percent today. 

Meanwhile the Tea Party movement, irrespective of Palin's decline in favorability, is faring better than ever. According to the same poll, 32 percent of Americans — up from a previous high of 31 percent in June — now consider themselves Tea Party supporters. This includes 30 percent of independent voters. Another 25 percent of independents, along with 57 percent of Democrats, say they oppose the movement.

The poll was conducted Nov. 4-7 by Gallup and has a four-point margin of error.
