Although being left behind in the national polls and demanded by Obama's supporters to drop out the race, the former First Lady insisted that she would continue with the campaign to the Democratic presidential nomination convention late August.
However, Democratic leaders have urged for an earlier end of the presidential race for fear the tie between Obama and Clinton would split the party and compromise its odds-on in the November general elections.
The Gallup's poll also showed a virtue tie between both Democratic hopefuls and the presumptive Republican nominee, John McCain, who led Obama by 46 percent to 45 percent and beat Clinton by 47 percent to 45 percent.
The poll has an error margin of 3 percentage points.
