(CNN) - One in four Americans have a favorable opinion of Sarah Palin according to a new poll out Thursday that measures the former Alaska governor's popularity.
Of the adults surveyed in the CBS poll nearly half, or 48 percent, view her unfavorably. But Republicans are more likely to have a favorable view of Palin than Democrats, 44 percent to six percent.
Although she hasn't ruled out a run for the White House in 2012, 64 percent of those polled do not think she would be an effective president, with eight percent of Democrats and 39 percent of Republicans saying she would make a good president.
But the numbers change when Tea Party members are polled. Forty seven percent of members think she would make an effective president.
Among likely voters, a Tea Party affiliation is a positive voting factor among 32 percent of Republicans and only four percent of Democrats.
Palin has endorsed candidates throughout the midterm election season and uses her political action committee, Sarah PAC to contribute to candidates across the country. She made a speech in Iowa in September, further fueling the chatter that she will launch a presidential bid for the 2012 election. Palin will team up with Republican National Committee Chairman Michael Steele at two rallies in October.
