A majority of Americans oppose sending additional troops to Iraq as outlined by President Bush in his nationally televised address Wednesday night, and just one-in-three Americans said the plan for more troops and a stepped up combat efforts by Iraqi forces make victory there more likely, according to a new Washington Post-ABC News poll.

The findings of the survey, conducted after Bush's primetime speech, represent an initial rebuke to the White House goal of generating additional public support for the mission in Iraq. The poll found that 61 percent of Americans oppose sending more than 20,000 additional troops to Iraq, with 52 percent saying they strongly oppose the plan. Just 36 percent said they back the president's new proposal.

Bush fared better among the 42 percent of Americans who actually watched the speech. Among that group, 47 percent support sending more troops, while 51 percent oppose. But the President's supporters were disproportionately represented among the audience.
