(CNN) - It was just over one month ago Hillary Clinton and Barack Obama made a much-hyped public display of unity at a New Hampshire campaign stop. But more than 30 days later, the New York Democrat has rarely been seen at Obama's side, and she's only attended a handful of events on his behalf.
The reason for her ostensible absence from the campaign trail? She has an important day job, said her former campaign chairman Terry McAuliffe.
"Since that meeting in Unity, New Hampshire, the Senate has been in session," McAuliffe told MSNBC Monday. “I've tried to get her to travel and do a couple of events. And she hasn't been able to do those yet."

Still in an election year where many Democrats feel so much is at stake, Clinton's relatively minimal public campaign role to date has been noticeable. It also comes amid continued resistance from many of her former supporters towards Obama's candidacy. Despite choreographed and carefully produced pictures of the two former rivals standing side by side last month, many of Clinton's top donors have yet to sign checks over to Obama, and some have even openly said they may not vote for him.
According to a CNN/Opinion Research Corp. poll released earlier this month, Clinton supporters who say they plan to vote for presumptive Republican nominee Sen. John McCain are down from a month ago, but those who say they plan to vote for Obama are also down, and a growing number say they may not vote at all.

But McAuliffe, one of Clinton's most aggressive supporters during the prolonged Democratic primary race, said the New York Democrat has been working vigorously for Obama behind the scenes, and is about to assume a more public role in the campaign.
"I don't like to relay conversations between Senator Obama and Senator Clinton - I know they have an extensive travel schedule for her," he said. "The requests have been piling up. Hillary Clinton has done more in her position of anybody that has come in second before. She's been working. She's been making calls. As soon as she gets done with her senate deals, she's going to hit the campaign trail."
Meanwhile, an Obama source tells CNN's Gloria Borger Clinton will hit the trail for Obama in three or four battleground states next month.
"She will do anything she can to help Barack Obama become the next president," he added.

Caveat is if they accept....
Vice President: General Wesley Clark
Department of Energy: Al Gore
Secretary of Defense: John McCain
Secretary of State: Hillary Clinton
Attorney General: John Edwards
Homeland Security: Joe Biden
If Hillary wants any kind of polital future, she will finish up in the senate and come out ont he campaign trail with Barack. Her supporters who think it's a good idea to let McCain win this year so that Hillary can win in 2012. . . what about the 18 million Obama supporters? She will need us in the future. Puma people have trouble looking at the big picture.
Not surprising. If she didn't go back to work in the Senate people would complain. I wouldn't be mad if she had taken a two-week vacation to a remote island just to recharge after the primaries.
Shhh...Hillary has joined my campaign. But don't tell anyone.
Wow, I'm just tuning in to all this. Who are the nominees going to be? I thought I'd wait for the conventions to find out. Is something happening for the presidential race already? I can't believe people are interested in this yet. I'm a political junkie, but why would anyone care about any of this until October?
Bet a buck, the Obamanation groupies have a field day with this one but forget the fact he is a pampas, arrogant person who thinks he OWNs this election just because.
Let's give this lady a break, afterall she has done more for Obama than Edwards (in my own view).
Though I was against her during the primaries, but with what she has done lately and shortly after losing such a strong battle, I really applaud her for her efforts for BO.
Hillary, stay far away from Obama as possible!!!!!
Lovely and incredibly intelligent...?!!?
More like narcissistic and unbelievably dishonest
She has not been around bc she knows Obama is a lying fraud...Why should she be forced to support someone not worthy of the presidency? The DNC stabbed her in the back and I dont blame her one bit. I hope she doesnt lift one finger to help that man...
Hillary should start working out so that she could show her body off in something other than an pant-suit. Now that would be hot!!!
Once a liar always a liar, she never intended to campaign for Barack.
Hillary is home pouting! All of a sudden her day job is important but it took second fiddle while she had a chance at the nomination! She just doesn't want to campaign for Obama, period. She's a phony and it's all about her. I hope she stays gone and doesn't emerge in any type of important position with the new President. She needs to just fade away with Bill and stay faded away!
John McCain is going to be our next president. This year the moderates are finally going to have their day in the sun. Throw the liberals and conservatives under the bus. It's about time.
I fully supported Hillary and I wish she would have won. The fact that she didn't does leave us voters in limbo. However being an Amercian that wants to see things chnage I can not justify in NOT voting because that will not help anything. I think we all need to get behind Obama at this point. If he selects her as his running mate (which I hope he does), I truly believe they will be an unstoppable team. This is whineing for her, it's facing the facts.
LOL @ PUMA-PAC-HUSSEIN
Puma Puma Puma, you people are loosers.. Your canidate has thrown in the towel, stop blaming everyone else for your failures... Get with the program, you all whine like spoiled brats. Get over yourselves... Just had a thought!! I think i might start an anti-Puma organization..
He cant' win without her.
Hillary knows what any intelligent person does. Obama is far from the best qualified person to be president. The only thing worse would be to elect a Republican.
It's come down to choosing the lesser of 2 evils. That's why Clinton supporters are so upset–we no longer have a decent option for president.
No wonder so many are apathetic.
PUMA-PAC – Hussein be serious.
Hillary ran a great campaign but she lost by the rules. The DNC rules committee did its job and those who think that hillary will be the nominee has lost it. There is no way the American public will embrace her in such a way after we had months as Obama as trhe nominee. She would lickly lose and would cause another 8 years of bush.
Obama/Clinton or no Obama.
This is not a whine for Clinton, this is a deep concern for supporting someone, Obama, who has little experience, questionable friends, belonged to a black liberation church for 20 years where the pastor preached words of hate and racism. Yes, Obama gives a fantastic speech, and yes he is smart and yes, his Chicago team has run a great campaign. But we need more than looks and a slick campaign in a President and I need a President the represents my core values which are not hate and racism.
Obama doesnt even need clinton to win......
"Angry Clinton Supporters" is simply a media-hyped story about a few die-hard Clinton fans. No way these supposed "angry Hill-raisers" vote McCain or don't vote, thus letting the Supreme Court be stocked with conservatives for the rest of their lifetimes. They're not that stupid, so please MSM, stop making a story up like this. And for god's sake, shut up this PUMA-PAC Hussein idiot.
It would be nice for Hillary if she would keep her word. She said she was going to back Barack – and we are waiting to see that.
Let her sleep it off for a long time. She needs it.
