Sanders is the only choice for President of The US as far as I see it. The middle class is disappearing, and we need too rebuild our infrastructure. Bernie Sanders is the only person addressing these fundamental issues. He's also the only candidate who genuinely is for the people, and his campaign proves it with how much money he's received as donations from average working class Americans, as opposed to lobbyists and corporations.
The other thing that I'd like to address about Sanders is that he is a Democratic Socialist, not a Socialist. These are two different things, and people just assume he's a Socialist while totally ignoring the Democratic part. Historically, Socialism is not a democratic process, and was often imposed upon citizens with violent force. Sanders makes it clear that he has nothing to do with the Socialists of yesteryear, and insists that Socialism in America should be chosen freely and fairly by the electorate.
