Hillary Clinton's campaign Wednesday pounced on Sen. Barack Obama's acknowledgment that he has yet to hold a substantive hearing since becoming chairman of a Senate subcommittee on Europe.

The admission during Tuesday night's Democratic debate offered a "glimpse of the real Barack Obama," and was emblematic of the Illinois senator's light record of results, the Clinton camp said in an e-mail.

Obama "did not hold a single oversight hearing because he was too busy running for president; the Barack Obama who spends his time talking about change you can believe in instead of change you actually can count on," the e-mail stated.

Clinton herself raised the issue at the debate in Cleveland.

'"He chairs the subcommittee on Europe. It has jurisdiction over NATO. NATO is critical to our mission in Afghanistan," she said. "He's held not one substantive hearing to do oversight, to figure out what we can do to actually have a stronger presence with NATO in Afghanistan."

In response, Obama noted he has only served as the committee's chairman since January of 2007, just when his presidential campaign was beginning - a fact the Clinton campaign's memo also highlighted.

"But by his own admission, he was too busy running for president to conduct a single substantive hearing of the committee he chairs," the memo stated. "So he would rather talk about what he would do rather than do it through the responsibility he had.”

For the record, Obama has held two hearings on ambassadorial nominations, but no oversight hearings.

Hillary Clinton told a gaggle of reporters on board her airplane during a flight from Cleveland to Columbus that at this late stage of the primary race, "people are really rallying to my candidacy."

Clinton said she was "really pleased" with her debate performance in Cleveland, arguing that she was able to  present "some real contrasts" against Barack Obama, especially on the issues of health care and the economy.

"What I feel is happening is that people are turning towards the big questions that we should have to answer in this campaign," she said. "Give me the best Commander in Chief. Who do you want in the White House answering the phone at three a.m.? Who is the best steward of the economy?"

Clinton said that along with getting a second look from voters, her campaign continues to raise $1 million a day over the internet, a factoid she has been touting since Super Tuesday.

Despite that cheery forecast, her campaign sent out a fundraising e-mail Wednesday from Bill Clinton that accused Obama of trying to drown out his primary opponent with a barrage of TV ads.

"So let's show the Obama campaign that they can't win this race just by throwing more money at it," the email said, seeking to raise $1.9 million in the next 24 hours.

Clinton is hosting an "Economic Solutions Summit" in Zanesville on Wednesday, followed by two rallies in the towns of St. Clairsville and Belpre. She heads to Texas late Thursday for the remainder of the week, hitting the major media markets of Houston, San Antonio and Dallas/Fort Worth.

“John McCain may like to say he wants to follow Osama bin Laden to the gates of hell, but so far all he’s done is follow George Bush into a misguided war in Iraq,” Obama said.

Earlier, McCain released a statement that attacked Obama for his comments at Tuesday’s debate that were critical of the Iraq war.

"Last night, we also heard Sen. Obama say that once he withdrew US forces from Iraq he would 'reserve the right' to act 'if Al Qaeda is forming a base in Iraq,'” McCain said in the statement. “Is Sen. Obama unaware that Al Qaeda is still present in Iraq, that our forces are successfully fighting them every day, and that his Iraq policy of withdrawal would embolden Al Qaeda and weaken our security?

“Where is the audacity of hope when it comes to backing the success of our troops all the way to victory in Iraq? What we heard last night was the timidity of despair. Our allies deserve better, our soldiers deserve better, and so do the American people."

During his appearance at Ohio State University, Obama accused McCain of trying to score cheap political points.

“McCain thought that he could make a clever point by saying 'Well, let me give you some news, Barack, al Qaida IS in Iraq,' like I wasn’t reading the papers, like I didn’t know what was going on. …”
