The Latest New Hampshire Numbers

After a strong third place showing in the Iowa caucuses, Florida Sen. Marco Rubio is getting a post-Iowa boost in New Hampshire polling. ABC's RYAN STRUYK reports Rubio is now in second place in the Granite State, according to two recent polls from CNN/WMUR/UNH and University of Massachusetts Lowell, conducted after Monday's Iowa caucuses. In a University of Massachusetts-Lowell tracking poll released Thursday, Trump sat on top of the pack with 36 percent support, but Rubio had 15 percent support -- up from 8 percent in the same poll. http://abcn.ws/1mgVegt

ANALYSIS -- ABC's RICK KLEIN

If Jeb Bush goes down, he won't go down without his family. Throwback time is in full gear, with former first lady Barbara Bush coming out to a "Beach Boys" song at an event for his son in New Hampshire, and former President George W. Bush appearing in an ad for his brother paid for by his Super PAC. (No "coordination" there, surely.) Beyond the past, though, there's reason to think New Hampshire isn't Jeb's last stand after all. Among the three governors who've gone all-in here, he's the one with the most resources and strongest organization in the states coming up - including South Carolina, where it's likely that his brother is put into service. John Kasich and Chris Christie need to beat each other, functionally, in addition to Jeb Bush; Bush can most likely afford to just keep it close. That, though, doesn't account for the Marco Rubio factor. With polls showing Rubio surging late in the Granite State, pressure will build for the establishment to coalesce. It will be master and apprentice battling it out yet again.

Barbara Bush Brings Her Flair to Jeb's Campaign

As Barbara Bush hits the trail for her son, Jeb, the former First Lady is campaigning for the first time in almost a decade. With her visit comes a new jolt of life into her son’s campaign...and all the exuberance that comes with the opinionated matriarch of the family. As she spoke with families, she joked with a mother who said that her kids were “easy." “They’re easy?” Bush asked. "Mine weren’t. In fact, mine occasionally fought. Not argued. I mean literally fought,” she said. She then vented about her frustrations with her husband. “He may not agree with me but he will not argue — it’s very frustrating,” she said. http://abcn.ws/1L3WoCw
