CNN Correspondent: Warren Is Struggling to Stay Relevant

A CNN correspondent said Sen. Elizabeth Warren (D., Mass.) is struggling to stay relevant in New Hampshire as primary voting is underway in the state.

"For Elizabeth Warren, it's been a struggle to really remain relevant, frankly. She has had a hard time building a level of support she expected, being someone from nearby Massachusetts," Ryan Nobles said during a report from the state Tuesday morning.

He also said that Warren and Sen. Bernie Sanders (I., Vt.) have taken different approaches to criticize their fellow Democratic presidential candidates.

"Sanders [is] not afraid to go after who he right now views as his chief rival in Pete Buttigieg, hammering his donor base, suggesting that it would influence his presidency," Nobles said, "while Warren, even though she's struggling in the polls right now, continues to remain above the fray, arguing that what the Democrats need to beat Donald Trump is a unity candidate. Even though she's struggling at this point, she's not trying to bring down her other opponents."

Nobles said that Sanders has solidified his support from the 2016 New Hampshire primary where he defeated eventual nominee Hillary Clinton.

Results from early voting in the state show Sen. Amy Klobuchar (D., Minn.) in the lead. Recent polling showed Sanders leading with 29 percent support in the state. Former South Bend, Ind., mayor Pete Buttigieg came in second with 22 percent support, and former vice president Joe Biden came in third with 11 percent, edging out Warren who had 10 percent.
