And there is the hook:
Sen. Timothy M. Kaine of Virginia and Agriculture Secretary Tom Vilsack remain two of the leading contenders for Hillary Clinton’s vice-presidential pick, but Sen. Cory Booker of New Jersey is also under active consideration, according to a Democrat with knowledge of the process.
Booker, a freshman senator and former mayor of Newark, has drawn relatively little attention throughout Clinton’s vice-presidential selection process but remains a serious prospect. He was among the roughly half-dozen potential running mates who met with Clinton at her home in Washington on Friday, a fact first reported Thursday by Politico.
Please let this be the hook.
On Sen. Booker (D-NJ): It is easy enough to say if not Warren then Booker. But neither is Mr. Booker a second choice for lack of better. Nor, in that context, should we view Sen. Kaine (D-VA) or Sec. Vilsack (D-IA) so poorly. 
But in the case of the latter, Hillary Clinton can at least perceive the need for someone less institutionally ensconced than either of these stalwart political résumés offer the powerful left-flank movement asserting policy influence, a bloc whose votes and continued support she needs.
Sen. Warren (D-MA) seems the obvious choice, but truth told there is a fine argument for what she can do from the Senate, but this also presumes enough pressure on Democratic leadership in the Senate to buck future Democratic Leader Charles Schumer (NY) and Whip Richard Durbin (IL). It’s a tough proposition, but the Senate Democrats under Elizabeth Warren and Patty Murray (WA) or Amy Klobuchar (MN) would be a powerful majority caucus; as a minority, it seems an easy suggestion that they would be more effective than what Mr. Reid (NV) has managed in the face of Republican intransigence. It’s all speculation, though. The bottom line is determined by Hillary Clinton, this time; she can perceive the need, but how will she address and reconcile it?
Elevating Sen. Booker as her running mate is one of the things she can do. And should anyone find cause to doubt we are getting civil rights president out of this, selecting Mr. Booker would put that question to rest.
