(CNN) – A day after Sen. Hillary Clinton declared that the Democratic nomination fight was “nowhere near over,” polling data released Tuesday suggest Clinton is losing ground with key demographic groups that have powered her campaign so far.
Sen. Barack Obama’s 16-point lead over Clinton in the latest Gallup daily tracking poll of Democrats and Democratic-leaning voters comes from even higher support among groups that have been supporting him throughout the primary race, and from newfound support among several groups that have backed Clinton.
Obama leads or ties Clinton among women, Easterners, whites, adults with no college education, and Hispanics, with the New York senator’s support now below 50 percent in each group, according to Gallup. Both are backed by 47 percent of white voters surveyed, and Obama is essentially tied with Clinton – 47 percent to 46 percent – among Democrats whose education level is a high school diploma or less.
Clinton’s advantage among women overall seems to have evaporated, with Obama now holding a lead within the survey’s three point margin of error, 49 percent to 46 percent. Hispanics favor Obama over Clinton by 7 percentage points, 51 percent to 44 percent. And Obama now leads among voters in Eastern states by 9 percentage points over Clinton – 52 percent to 43 percent.
Clinton’s standing with whites has fallen by five percentage points during the month of May. With Hispanics, Clinton has lost eight percentage points in the same time period. Clinton’s support with Easterners has fallen by seven percentage points and with women, Clinton has last four percentage points in May. Women age 50 or older is the only major demographic group where a majority, 52 percent, still support the New York senator.
Obama’s support among voters with postgraduate education, voters with monthly incomes of at least $5000, and men – has grown to the point that, he now leads Clinton by a margin of 2-to-1. Among voters 29 or younger, Obama leads Clinton by a margin of nearly 3-to-1.
Gallup’s results released Tuesday are based on a survey of 1,261 Democratic and Democratic-leaning voters using combined data from May 16-18, 2008. The survey has a margin of error of plus or minus three percentage points. Gallup’s May 1-13 daily tracking poll results are based on a survey of 5,474 Democratic or Democratic-leaning voters. The May 1-13 survey results have a margin of error of plus or minus one percentage point.
