The Dems and the elites who back them are looking to see if Clinton Corruption has legs. If it does, her poll numbers will continue to decline. At some point, if the Dems determine that she cant win in 2016, you will see the dogs turned loose: The Loretta Lynch justice dept will launch an investigation and find significant and illegal wrongdoing, the MSM will savage Hillary, and in parallel one or more new candidates will emerge. I would expect Elizabeth Warren to get the anointing since she is an extreme leftist supported by Beeho. Hillary's political career will be over. Although the Dems are amazing efficient and unified on the outside, they have their factions just like the Repubs and the "Clinton machine" has many enemies within the party, and in the administration as well.

For Dems its 100% about winning elections and the political calculations that go into that. Hillary's increasing baggage may be too much of a risk.
