Hillary is not mainstream. She's not even on the far left bank of the mainstream.
She is way, way out there --a genuine '60s girl, and the ideas and staff she would bring to the White House would represent a sharp break with all that has gone before in American politics.
With as many as six appointments to the Supreme Court in the next eight years (six Ruth Bader Ginsburgs!) a Hillary Court would be like a Hillary presidency--a radical Bench to back up a radical Administration.
That's the 2008 campaign in a nutshell.
