Hillary Clinton was again presented with the Keystone XL Pipeline expansion issue during her campaign in Nashua, N.H. on Tuesday. Clinton has once again not decided whether to support the project or not. The Keystone oil pipeline systems run from Canada to the United States and has been in the works since 2010.

A Nashua voter present in the meeting, Bruce Blodgett, asked, "As president, would you sign a bill, yes or no please, in favor of allowing the Keystone XL pipeline?" Blodgett, a software developer from Amherst, N.H., is in favor of the pipeline construction since he believes that the oil will be used, so it might as well be transported to the United States, CNN reported.

Clinton answered, "This is President Obama's decision and I'm not going to second guess him". "If it's undecided when I become president, I will answer your question," she added. Her answer stunned the 450 people participating the event inside the humid Amherst Street Elementary School. In her recent similar event in New Hampshire, climate change supporters have questioned her extensively about her neutral stand on the Keystone Pipeline issue, according to the New York Times.

Climate change proposals would be the focus of Clinton's campaign, she announced Monday. If she wins the presidential race; by 2027 she wants each American home be sustained through renewable energy. She plans to install 500 million solar panels around the United States and incentivize all kinds of renewable energy, said on the Huffington Post.

Fellow Democratic running mates, ex-Maryland Gov. Martin O'Malley and Vermont Sen. Bernie Sanders, have expressed opposition to the expansion of the Keystone XL Pipeline. "It is hard for me to understand how one can be concerned about climate change but not vigorously oppose the Keystone pipeline," Sanders said Tuesday, according to CNN.
