Support for building the Keystone XL pipeline is now at its highest level ever.

The latest Rasmussen Reports national telephone survey finds that 61% of Likely U.S. Voters now at least somewhat favor building the major oil pipeline from Canada to Texas, while just 27% are opposed. This includes 37% who Strongly Favor the project and 10% who Strongly Oppose it. Thirteen percent (13%) are undecided. (To see survey question wording, click here.)

Support for building the pipeline is up four points from 57% in January and now has edged above the previous high of 60% found in November 2011 when President Obama first delayed the project for further environmental study.

The Obama administration announced last Friday that it is delaying a decision on building the Keystone pipeline until after the Nebraska Supreme Court rules on a legal challenge. Supporters of the Keystone project claim the administration is deliberately postponing the decision until after Election Day.
