From the Morning Memo:

U.S. Sen. Kirsten Gillibrand appeared to enter the Democratic presidential debate with a clear strategy: Stand out on a crowded stage.

Gillibrand was assertive, muscling her way into the conversation when she wasn’t asked a question. She sought to make a point about straddling a middle ground between Sen. Bernie Sanders’s democratic socialism and former Vice President Joe Biden’s effort to sustain and expand Obamacare.

After night one of the debates featured men mostly interrupting women, Gillibrand wasn’t timid about interrupting the men on the stage.

But as Gillibrand sought to make some wonkish points about her record in the Senate, her efforts were overshadowed by the big moment of the night: California Sen. Kamala Harris blasting Biden over his school busing stance in the 1970s.

The moment is being seen as a potential tipping point for Biden, given his strong support from black voters, and for Harris as well, as she has been considered a slow, but steady campaigner.

Gillibrand’s campaign has struggled in fundraising and in the polls. As the criteria rises for entree into the next debate, the impression she made on voters on Thursday night may have been all the more important.
