Martin O'Malley looks like he's about to throw his hat in the ring. He has a few things that may make him a thorn in Hillary Clinton's side, including a willingness to go after her indirectly before he even announces his candidacy.

He is being called a "Rock 'n Roll" candidate that is young, ideologically left of Clinton, and ideologically right of Bernie Sanders. Is he going to do to Clinton what candidate Barack Obama did in 2007-2008, sneaking up and blowing right past her? Can he pull in some far left votes from Sanders while still pulling from the middle?

Is he the real frontrunner that most mainstream voters aren't even familiar with yet?
