Americans support the idea of constructing the Keystone XL oil pipeline between Canada and the United States by a nearly 3 to 1 margin, with 65 percent saying it should be approved and 22 percent opposed, according to a new Washington Post-ABC News poll.

The findings also show that the public thinks the massive project, which aims to ship 830,000 barrels of oil a day from Alberta and the northern Great Plains to refineries on the Gulf Coast, will produce significant economic benefits. Eighty-five percent say the pipeline would create a significant number of jobs, with 62 percent saying they “strongly” believed that to be the case.

At the same time, nearly half of those interviewed — 47 percent — say they think Keystone will pose a significant risk to the environment.
