Liberals press Hillary Clinton for policy specifics

Liberal groups say Hillary Clinton is a blank slate when it comes to certain policies and are pressing her to side with them on the Keystone XL pipeline, deportations, financial regulation and other matters.

The push for Mrs. Clinton to flesh out her views comes as she has stepped up her public appearances ahead of a likely campaign for the 2016 Democratic presidential nomination. She has addressed college audiences in recent months, said goodbye to TV personality Barbara Walters on the set of the “The View,” and spoken to policy groups, such as the American Jewish Committee.

At some of those events, Mrs. Clinton has moved to shore up her foreign policy stances—sounding tough notes on Iran and Russia. But she has dipped into policy debates selectively, and the liberal groups want more details on where she stands on a range of matters.

On Wednesday, a collection of 30 environmental groups sent Mrs. Clinton a letter asking her to oppose the Keystone XL project, which would carry oil from Canada’s oil sands to U.S. Gulf Coast refineries.

“I think she’s been conveniently coy on Keystone. We’d like her to be much more definitively against the project,” said Bill Snape, senior counsel at the Center for Biological Diversity, which signed the letter.
