While the Obama administration mulls whether to approve the controversial Keystone XL pipeline, Americans are already decided. They support the project by a wide margin, prioritizing potential economic benefits over possible environmental consequences.

The latest United Technologies/National Journal Congressional Connection Poll finds that more than two-thirds of respondents, 67 percent, support building the pipeline to carry Canadian oil to refineries on the U.S. Gulf Coast; that includes 56 percent of Democrats. Less than a quarter of Americans, 24 percent, oppose the project, the poll shows.
