“I am not sure what value it would bring to have her run,” said Wayne Shields, CEO of the Association for Reproductive Health Professionals, who, along with Warren’s husband, hosted Warren at his house earlier in her Senate candidacy. “She would be such a target for conservatives, it may end up having a paradoxical effect on Democrats.”

One Massachusetts Democrat, who helped lay the groundwork for Warren’s Senate run back when Warren was a Harvard professor mostly known as a thwarted nominee to the newly created Consumer Finance Protection Bureau, agreed:

“If she ran, it would tear apart the Democratic base even worse than Hillary and Obama did. Whoever is pushing this is not doing the Democratic Party any favors, and I wish it would stop.”

That feeling, and it is one echoed in other conversations among the donor class, is that a Warren run would expose divisions in the Democratic Party—between, in Adam Green’s words, the populist and the corporate wings—that have lain largely dormant on the national level as Democrats fear a Tea Party-controlled executive branch.
