CBS News Poll analysis by the CBS News Polling Unit: Sarah Dutton, Jennifer De Pinto, Fred Backus and Anthony Salvanto.
Ahead of a rally in Washington this weekend that some say will test the strength of the Tea Party, a new CBS News poll finds that 29 percent of Americans say they are supporters of the movement.
Fifty-four percent say they do not support the Tea Party. The survey results are similar to last month's but show more support for the Tea Party than in April of this year.
Fifty-six percent of Tea Party supporters say they are conservative. Forty-four percent are Republicans, while 43 percent are independents. Few - just 13 percent - identify themselves as Democrats.
Conservatives and those who identify themselves as supporters of the Tea Party movement hold net positive opinions of former Alaska Gov. Sarah Palin, who has championed the movement. Forty-five percent of Republicans, 41 percent of conservatives and 49 percent of Tea Partiers hold favorable opinions of Palin.
However, Palin continues to receive unfavorable ratings from the American public overall. Just 23 percent of Americans have a favorable opinion of Palin, while 40 percent view her unfavorably.
Democrats (62 percent), moderates (44 percent) and liberals (61 percent) hold decidedly negative views of the former vice presidential nominee.
More than a third of the public (35 percent) is undecided or hasn't heard enough about Palin to offer an opinion. Fewer Americans now hold a favorable view of Palin than in April, but her ratings are similar to what they were in March and last summer, shortly after she stepped down as governor.
