The Senate voted 62 to 37 Friday in favor of constructing the Keystone XL pipeline, the controversial project that would transport heavy crude oil from Hardisty, Alberta, to Gulf Coast’s refineries.

The bipartisan amendment to the Senate budget resolution, authored by Sens. John Hoeven (R-N.D.) and Max Baucus (D-Mont.), has no binding authority. But it shows the significant support the proposal enjoys on Capitol Hill, despite the fact that opponents argue its construction will accelerate global warming and could cause harmful oil spills on ecologically-sensitive habitat.

The 17 Democrats who voted yes included every single possibly vulnerable incumbent facing reelection next year, from 34-year veteran Baucus to first-term Sen. Mark Begich (Alaska).
