While Ms. Clinton voted for the invasion of Iraq, Mr. O'Malley has been a longtime critic of the Iraq War. As governor, Mr. O'Malley sponsored and signed a same-sex marriage bill when Hillary Clinton was overtly against gay marriage. He also signed a marijuana decriminalization bill, while Ms. Clinton has said she was against the decriminalization of marijuana. Martin O'Malley wants to bring back Glass-Steagall, called the Trans-Pacific Partnership a "bad trade deal," and urged the Senate in 2014 to reject the Keystone XL pipeline. Hillary Clinton, on the other hand, once referred to TPP as "the gold standard in trade agreements," and she still hasn't taken a stance on the Keystone XL pipeline.
