Poll: Majority Support Keystone Pipeline

Pew poll also shows increased belief in global warming


Two-thirds of U.S. residents support construction of the proposed Keystone XL oil sands pipeline, including an apparent majority of Democrats, new Pew Research Center polling shows.

The same poll released Tuesday also shows increasing belief in global warming in recent years, but a dip from 2012 in the share of people who consider it a "very serious problem."
