(CNN) – A new Gallup poll suggests more than half of the country may support a proposal backed by President Bush and Sen. John McCain to allow states to authorize off-shore oil drilling, a practice currently banned by the federal government.
Fifty-seven percent of Americans favor allowing oil drilling in coastal and wilderness areas that are currently off-limits. Forty-one percent of Americans oppose allowing drilling in those areas, and 2 percent have no opinion.
The poll also reveals a partisan divide on the issue. Eighty percent of Republicans surveyed favored opening up off-limits areas to oil exploration and 56 percent of independents favored allowing the practice. But 59 percent of Democrats opposed the idea.
During the last week, the prospect of oil drilling off the U.S. coast has become into a major policy dispute between Sens. John McCain and Barack Obama, respectively the presumptive Republican and Democratic nominees, and between Democrats and Republicans on Capitol Hill.
The Gallup survey involved telephone interviews nationally with 1,013 adults aged 18 and older and was conducted May 19-21. The poll has a margin of error of plus or minus 4 percentage points.
