As the Obama administration approaches a decision on the Keystone XL pipeline, a national survey finds broad public support for the project. Two-thirds of Americans (66%) favor building the pipeline, which would transport oil from Canada’s oil sands region through the Midwest to refineries in Texas. Just 23% oppose construction of the pipeline.
Support for the pipeline spans most demographic and partisan groups. Substantial majorities of Republicans (82%) and independents (70%) favor building the Keystone XL pipeline, as do 54% of Democrats. But there is a division among Democrats: 60% of the party’s conservatives and moderates support building the pipeline, compared with just 42% of liberal Democrats.
