A plurality of Democrats supports the building of the Keystone XL pipeline, though support is much lower among wealthier, more liberal and more educated members of the party, according to a new poll.

The Pew Research Center poll, as with other polls, shows broad support for building the pipeline, which the Obama administration is still reviewing. Sixty-one percent of people favor building it, while just 27 percent oppose it.

Democrats support it in smaller numbers, 49-38, but support varies widely based on several characteristics.

While 56 percent of conservative or moderate Democrats back the pipeline, just 40 percent of liberal Democrats do.

While 58 percent of Democratic men support it, just 43 percent of Democratic women do.

While 54 percent of Democrats with a high school degree or less back it, just 35 percent of Democrats with post-graduate degrees agree.

And while 54 percent of Democrats making less than $50,000 want to build the pipeline, just 36 percent of those making more than $100,000 do.

Republicans and independents support Keystone XL in strong numbers, including 61-29 among those not affiliated with either party.
