Sen. Barack Obama (D-ILL.) has been broadening his support among Democratic voters, with especially strong support among men, a new poll has found.

He is now viewed by most Democrats as the candidate best able to beat Sen. John McCain (R-Ariz.), the presumptive Republican presidential nominee in the general election on November 4, according to the New York Times/CBS News Poll released Tuesday.
