UPDATE 2/17: John Edwards and Barack Obama have finally had their private meeting in Chapel Hill:

Mr. Obama, who canceled an afternoon campaign trip to Wisconsin, flew to Chapel Hill, N.C., to meet with John and Elizabeth Edwards this morning. The meeting was quietly rescheduled after a session Monday with the two men was postponed because too much attention was being paid to it and camera crews were staking out Mr. Edwards' home.

Obama has said not to expect much out of the meeting:

"I don't think there's any imminent news," Obama told CBS affiliate WISC-TV this afternoon. "We were exchanging views, he was giving me some thoughts, and obviosuly he's gonna be a big force in the Democratic party for many years to come."

Campaign officials would not specify whether the meeting included a promise of an Edwards endorsement.

UPDATE 2/15: Edwards' top backers are tilting overwhelmingly to Obama:

Jim and Susan Phillips were loyal supporters of fellow North Carolina Democrat John Edwards and backed up their support with money. But a day after Edwards dropped out of the presidential race last month, Susan Phillips sent $500 to Sen. Barack Obama of Illinois.

"He is the most likely guy to bring people together and the guy with the most potential to fundamentally change the way we do business in the United States," said Jim Phillips, a Greensboro lawyer and chairman of the UNC system board of governors.

Of the $44 million Edwards raised through December, more than $2.6 million came from the Carolinas.

Interviews with nearly 20 of Edwards' top contributors in the Carolinas, selected randomly, showed a majority of them tilting toward Obama, with some undecided.

No contributors said they're ready to back Hillary Clinton.

UPDATE 2/13: John Edwards is "as split as the party he once hoped to lead -- and is seriously considering supporting Sen. Hillary Rodham Clinton, despite the sharp criticism he leveled at her on the campaign trail, according to former aides and advisers," ABC News reports:

In deciding between his one-time rivals, Edwards appears deeply divided. Several former advisers likened his thought process to a heart-versus-head split -- with his heart favoring Sen. Barack Obama's strong message of change, and his head attracted to Clinton's tested nature and commitment to tough fights.

Though he sometimes aligned himself with Obama -- and against Clinton -- as a candidate, several Edwards campaign insiders say the former senator began to sour on Obama toward the end of his own campaign, and ultimately left the race questioning whether Obama had the toughness needed to prevail in a presidential race.

"He is much more torn than people realize," said one former aide who has stayed in contact with Edwards. "Honestly, he has serious reservations about both of them."

UPDATE: Tonight's meeting between Obama and Edwards has been postponed, according to ABC's Political Radar:

While it is unclear which party ultimately pulled the plug on tonight's meeting between Obama and Edwards, sources indicate the meeting will be rescheduled in coming days.

No cause was given for the abrupt rescheduling but sources have indicated that the Obama campaign and Edwards wished that the meeting would be done in private without massive media attention.

Former Sen. John Edwards "met with Hillary Clinton Thursday in North Carolina, and is meeting with Barack Obama Monday, to discuss a possible primary endorsement." CNN reports:

The Thursday meeting, which took place at Edwards' home in Chapel Hill, was followed by a Saturday night session during which the former North Carolina senator and several longtime advisers discussed many issues, including which candidate he should endorse. [...]

At a Chapel Hill party yesterday for Edwards supporters, he gave no indication who he might endorse, or whether that endorsement is imminent. Some advisers are encouraging him not to endorse.

The former candidate is weighing a number of considerations before making his choice - including electability, and who will best promote his ideas.

There are policy considerations at play: there is a sense within the Edwards camp that Clinton's policies could be better for working class Americans. But Obama's anti-lobbyist proposals are more aligned with Edwards' politics.

In response to a CNN report that Elizabeth Edwards may favor Obama over Clinton, sources close to the Edwards family flatly deny that she favors one candidate over the other.

Greg Sargent at TPM Election Central spoke to an Edwards aide who offered more details, including: "There's a greater than 50% chance he will endorse."

The Edwards aide cautioned against reading too much into the meetings, saying that he'd been talking to both of them before. "He's torn," the aide said "He has reservations about Hillary, which are pretty apparent."

On Obama, the aide says, Edwards worries "whether he's tough enough to be President of the United States. If you look at what Edwards ran on, which is not negotiating with the special interests, taking away their power, that's pretty different than the Obama model."

The Edwards aide added that Obama's lack of a health care plan with a "mandate" is a "tough hurdle for him to get over." He added, however, that Edwards is much more in line with Obama on other issues.
