自由派参议员桑德斯进入2016年总统竞选

U.S. Senator Bernie Sanders of the northeastern state of Vermont says he will seek the 2016 Democratic presidential nomination.

Sanders revealed his plans in interviews with the Associated Press and USA Today. He will hold a press conference Thursday to further outline his plans.

The 73-year-old self-described socialist is a registered independent, but has been part of the Senate Democratic caucus since he was first elected in 2006. Along with Massachusetts Senator Elizabeth Warren, Sanders has become a favorite in the Democratic Party's emerging left wing for his stands on such issues as alleviating income inequality, strengthening Social Security, imposing tougher regulations on Wall Street and opposition to free trade deals, including the Trans-Pacific Partnership currently being negotiated by President Barack Obama.

Sanders is considered a longshot against former secretary of state Hillary Clinton, the only other declared candidate for the 2016 Democratic nomination, but his entry into the race could force Clinton to adopt views similar to those of Sanders.
