Elizabeth Warren’s good news for Bernie Sanders fans

[Raine1967]

5. You know, it could be good news for O'malley supporters as well.

They did not say they would support Sanders.
From your first link (the politico one) this was to entire headline:

Top pro-Elizabeth Warren group says she’s out
As Run Warren Run closes down, Sanders and O’Malley fight to claim its mantle.

Run Warren Run, the effort jointly operated by the liberal groups Democracy for America and MoveOn, will shut down Monday after delivering its final petition to Warren’s Senate office. Warren, the bank antagonist and liberal hero who has said from the start that she has no plans to run for president in a field that now includes Hillary Clinton, Bernie Sanders and Martin O’Malley, hasn’t budged.
The organization’s recognition that the Massachusetts senator truly won’t run is a significant shift in the Democratic presidential contest, in which Warren has been a shadow candidate even as she has repeatedly insisted she would not pursue the White House. But the prime driver of pro-Warren enthusiasm is acknowledging that its time and resources would be better spent influencing the national discussion in another way entirely, while Sanders builds grass-roots momentum and O’Malley ratchets up his campaign by targeting liberals.

The group — which has been getting less and less attention as actual candidates enter the race and jockey for Warren supporters — will shift its focus to supporting the senator’s legislative work that effectively pressures the front-runner Clinton from the left, starting with opposition to fast-track trade deals.

They are not saying they support Sanders.
