Well, it is still Maryland.
However, I don't think that-outside of an artificially (racially) gerrymandered congressional district and a former civil rights organization that has been hijacked by the fringe of the Dem. Party-he could win a single elective office throughout this great land.
A better analogy-than a comparison between him and Mikulski, or a similiar hard core leftist that has been repeatedly endorsed by the Maryland electorate-would be one that compares his career with that of Cynthia McKinney.
Unpalatable to the vast majority of sane voters, to the point that, if he ran against Alan Keyes, he would probably lose.
