Biden and Warren disappoint in New Hampshire primary

• Klobuchar seems likely to finish in the top three Tuesday night.

Between the lines: Biden saw the writing on the wall in New Hampshire. Expecting a low performance in the state, he opted instead to head to South Carolina Tuesday, where he's the long-standing front-runner.

• But his lead has been shrinking. While he once had a 31-point lead in South Carolina, a Post and Courier/Change Research poll from Feb. 2 showed him still in first, but with only a 5-point lead on Sanders (25%/20%).

And Warren still has reason for concern. Although she's set to come in fourth Tuesday, she was expected to do better in the first-in-the-nation primary. New Hampshire and her home state of Massachusetts share media markets, and she had geographically advantageous name recognition.

• But Sanders, whose home state of Vermont also neighbors New Hampshire, shared the same advantage.
