Update, September 22, 2015: Democratic presidential nominee Hillary Clinton has decided that she does, indeed, have an opinion on the issue. She is against the pipeline.

The original article continues below.

Hillary Clinton is a veteran of national politics and a two-time presidential contender—which is why America is baffled this morning as to why she doesn’t have a position on the Keystone XL expansion, the controversial proposed oil pipeline running from the Canadian tar sands to American refineries in the Gulf Coast.

During a campaign stop in New Hampshire, a man asked Clinton whether she’d sign a bill in favor of the pipeline, a project roundly criticized by liberals, environmentalists, and economists, but supported by those who say its construction would create jobs and boost trade with Canada.

Clinton, who was mildly involved in the project when the State Department ran an environmental analysis on the expansion, said that she could not answer that “yes or no” question due to a conflict of interest.

“This is President Obama’s decision and I am not going to second-guess him, because I was in a position to set this in motion,” Clinton elaborated. “I want to wait and see what he and Secretary Kerry decide. If it is undecided when I become president, I will answer your question.”

She explained her silence to The New York Times as a desire to recuse herself from, uh, something she did:

“I’m in a different position than any other presidential candidate — I served in this administration for four years,” Mrs. Clinton said, adding that the negotiations over the trade deal and the Canadian pipeline were continuing, and that she had been involved in those discussions as secretary of state.

“If you look at both the trade deal and the Keystone decision,” Mrs. Clinton said, “I will certainly express my opinion when there is something to express an opinion on.”

In the meantime, she repeated, “I do not think it’s appropriate for me to comment on something I had official responsibilities for until it is completed and that I might have official responsibilities for again.”

So far, the Obama administration has opposed congressional attempts to approve the pipeline, which was proposed in 2008. The State Department’s 2014 environmental analysis, however, found that while the project was unlikely to increase the rate of carbon pollution—the primary concern for environmentalists—the project actually would not create that many jobs.

CNN notes that Clinton herself has a history of avoiding questions about Keystone XL, ducking the subject whenever it came up on her book tours in 2013 and 2014.

As for the other candidates in the race? Martin O'Malley is against it. Bernie Sanders is (quite strongly) against it. Jeb Bush thinks it's a "no-brainer". Marco Rubio supports the pipeline (but missed a key vote to campaign). Rand Paul supports it. And so forth.

The rest of the candidates similarly run the spectrum of possible opinion on the pipeline, which makes Clinton’s lack of a position all the more confusing.
