None are close to moderate or progressive.
Everyone mentioned is far to the right of Dwight Eisenhower for God's sake.
Clinton signed NAFTA that destroyed millions of American jobs, but added trillions to the profits of corporations who moved those jobs to Mexico.
That's a Right Winger, and he has been repaid in millions and millions of dollars in "contributions" to his "Library",$1 Million Dollar "speeches", and seats on boards of manufactures companies.
Dodd has protected the boards of banks and corporations more the anyone else, providing weak, toothless regulations on banks and corporations to assure no actual oversight occurs.
He is repairs with Millions in contributions.
Elizabeth Warren is the only true moderate in the Senate- and she was not encouraged or supported to the extent she should have been, in fact, Obama refused to appoint to regulating position(s) because the banks hated her so.
Obama is Bush with a brain, and as long as Right Wing Wackos keep accusing him of being liberal, the actual Right Wing money folks just sit back and laugh at you all.
Some could infer this is a post of a far right winger from what he has said, but only if one forgets he is a Socialist.
The only inference one can get is the poster is totally confused in assuming a moderate is the same as a progressive when the "progressive" term is an euphemism for socialism, not a moderate stance at all.
