basically the only two democrats that seem like they are running for the democratic nomination for president against the inevitable candidacy of hillary clinton. in the most recent polls, potential candidate clinton leads by 47 and 48 points. martin o' malley has not polled above 2%. most recently he was at 1%. but if the match up is not going his way by several dozen points, well, the retirement of legendary senator barbara mikulski might offer a ticket to ride for him holding federal office. i think if she is interested in making a go for his seat.
