A new CBS News/New York Times poll finds Barack Obama with a 16-point lead over rival Hillary Clinton among Democratic primary voters nationwide.
Obama, coming off 11 straight primary and caucus victories, had the support of 54 percent of Democratic primary voters nationally. Clinton had 38 percent support.
In a CBS News poll taken three weeks ago, shortly before Super Tuesday, Obama and Clinton were tied at 41 percent. Clinton led by 15 points nationally in January.
The former first lady has lost her advantage among women, according to the poll: The two leading Democrats now have even levels of support among female primary voters.
