Read Federal election filings reveal chief backer of pro-Warren super PAC (TheHill)

The overwhelming majority of funds donated to a super PAC supporting Sen. Elizabeth Warren’s (D-Mass.) presidential bid came from a sole donor, according to new Federal Election Commission filings. 

Karla Jurvetson, a wealthy doctor in California, donated an eye-popping $14.6 million to Persist PAC, a group that sought to revive Warren’s faltering campaign in February.

The funds from Jurvetson made up the lion’s share of the roughly $15.1 million the super PAC raised last month in its efforts to boost Warren, who, prior to the group’s formation, had stumbled after third- and fourth-place finishes in Iowa and New Hampshire.

Read James Clyburn wasn't responsible for the Biden surge. So what was? by Kevin DrumKevin Drum (Mother Jones)
The green dot is February 29, the date of the South Carolina primary. Biden had gained a point or two before that, but he only really started to skyrocket shortly after the primary. So it’s safe to say that his big victory in South Carolina was the proximate cause of his early March takeoff. But what was responsible for Biden’s South Carolina win in the first place?

Biden went up a lot more, but he was taking votes away from Steyer, Warren, Buttigieg, and Klobuchar.
For now, the debate still seems the most likely cause. That’s a little unusual, since conventional wisdom says that debates don’t move public opinion much, but maybe this was an exception. 

Perhaps it was more the fact that the electorate just didn’t know or trust the Steyer, Buttigieg, and Klobuchar centrist crowd enough to vote for them with time running out. As a result the old tried-and-true guy you know pulls in all the people. He didn’t really need an inciting incident other than the looming election. Following the debate without anything else to use to make a decision on, the choice was *fait accompli*.
