FactCheck.org has a great analysis of the debate last night.

Here’s just the Summary for a quick perusal - but you really have to read the analysis:

• Obama said McCain adviser Henry Kissinger backs talks with Iran “without preconditions,” but McCain disputed that. In fact, Kissinger did recently call for “high level” talks with Iran starting at the secretary of state level and said, “I do not believe that we can make conditions.” After the debate the McCain campaign issued a statement quoting Kissinger as saying he didn’t favor presidential talks with Iran.
• Obama denied voting for a bill that called for increased taxes on “people” making as little as $42,000 a year, as McCain accused him of doing. McCain was right, though only for single taxpayers. A married couple would have had to make $83,000 to be affected by the vote, and anyway no such increase is in Obama’s tax plan.
• McCain and Obama contradicted each other on what Joint Chiefs of Staff Chairman Admiral Mike Mullen said about troop withdrawals. Mullen said a time line for withdrawal could be “very dangerous” but was not talking specifically about “Obama’s plan,” as McCain maintained.
• McCain tripped up on one of his signature issues – special appropriation “earmarks.” He said they had “tripled in the last five years,” when in fact they have decreased sharply.
• Obama claimed Iraq “has” a $79 billion surplus. It once was projected to be as high as that. It’s now down to less than $60 billion.
• McCain repeated his overstated claim that the U.S. pays $700 billion a year for oil to hostile nations. Imports are running at about $536 billion this year, and a third of it comes from Canada, Mexico and the U.K.
• Obama said 95 percent of “the American people” would see a tax cut under his proposal. The actual figure is 81 percent of households.
• Obama mischaracterized an aspect of McCain’s health care plan, saying “employers” would be taxed on the value of health benefits provided to workers. Employers wouldn’t, but the workers would. McCain also would grant workers up to a $5,000 tax credit per family to cover health insurance.
• McCain misrepresented Obama’s plan by claiming he’d be “handing the health care system over to the federal government.” Obama would expand some government programs but would allow people to keep their current plans or chose from private ones, as well.
• McCain claimed Gen. Dwight D. Eisenhower had drafted a letter of resignation from the Army to be sent in case the 1944 D-Day landing at Normandy turned out to be a failure. Ike prepared a letter taking responsibility, but he didn’t mention resigning.

Here’s just one example:

Boeing Boasts

McCain was went too far when he said, "I saved the taxpayers $6.8 billion by fighting a contract that was negotiated between Boeing and DOD that was completely wrong. And we fixed it and we killed it."

McCain certainly did lead a fight to kill the contract, and the effort ended in prison sentences for defense contractors. But the contract isn’t exactly "fixed" yet. In fact, questions have been raised about the role McCain has played in helping a Boeing rival secure the new contract.

After the original Boeing contract to supply refueling airliners was nixed in 2003, the bidding process was reopened. And in early 2007, Boeing rival EADS/Airbus won the bid the second time around. But Boeing filed a protest about the way the bids were processed, and the Government Accountability Office released a report that found in Boeing’s favor. In the summary of GAO’s investigation, the organization said there were "significant errors" with the bid process and that the directions given to Boeing were "misleading."

Further, the New York Times reported that "McCain’s top advisers, including a cochairman of his presidential campaign, were lobbyists for EADS. And Mr. McCain had written to the Defense Department, urging it to ignore a trade dispute between the United States and Europe over whether Airbus received improper subsidies." A liberal campaign finance group ran an ad hitting McCain on the connections back in July and our colleagues at PolitiFact found their attacks to be true, saying: "Center for Responsive Politics prepared a report for PolitiFact that backs [the charge] up. U.S. employees of EADS/Airbus have contributed $15,700 in this election cycle to McCain’s campaign."
