Martin O'Malley is in, he's boring as sin. Being a dull personality shouldn't preclude you from being President, as it isn't really in the job description to be entertaining, but it is what it is. His website vision is nothing but a word salad. "Support women and families", "Fight for better wages", "Strengthen our cities". I'm not sure what is going to differentiate himself here from any Dem, or Republican for that matter with some of those choices. He was also a big supporter of Hillary in '08, but now according to him, electing a Clinton is on par with crowning another in a royal family.
Lindsey Graham is also in for the Republicans. It seems his sole platform is talk about how we need more war, and to beat up Rand Paul in debates (assuming Graham can even get in one).
