Factcheck weighs in, full articles at factcheck.org:
Democrats:
Obama claimed we are "back where we started two years ago" in Iraq. Actually, all indicators of violence show dramatic improvement compared with two years ago.
Clinton repeated a misleading claim that the 2005 energy bill was "larded with all kinds of special interest breaks" for the oil industry. Actually, the bill resulted in a net increase in taxes on the oil industry, according to the nonpartisan Congressional Research Service.
Obama stated that U.S. medical care costs "twice as much per capita as any other advanced nation," which is incorrect. U.S. spending is double the average, but not double that of all others.
Clinton said there is no reason that U.S. troops should be in Iraq "beyond today," but she has also conceded that she might keep combat troops fighting there for years.
Richardson said the price of gasoline in New Hampshire is at a record high. It's close, but lower than he said, and lower than it was a few weeks ago.
In the analysis section we note further misstatements and twisted facts, and we find that Clinton was close to the mark when she criticized Obama for shifting positions on the USA Patriot Act
Republicans:
Romney claimed that the 47 million Americans who lack health care are not covered because they say "I'm not going to play. I'm just going to get free care paid for by everybody else." Experts say that very few who are offered insurance turn it down and that the uninsured get worse care.
Giuliani falsely blamed President Clinton for cuts in the military that occurred in large part under President George H.W. Bush and Secretary of Defense Dick Cheney. He said that ?the Army had been at 725,000; it?s down to 500,000.? That?s true, but it was down to 572,423 by the time Clinton took office.
McCain recalled that he "strongly disagreed" with Defense Secretary Donald Rumsfeld and had "no confidence" in his Iraq strategy "at the time." But he didn't say publicly that he had no confidence in Rumsfeld until December 2004, after Bush was reelected and well after the war began.
.
Romney falsely denied that an attack ad called McCain?s immigration bill "amnesty," though it does. One of his Web ads also attacks McCain for supporting "amnesty." He conceded during the debate that McCain?s bill "technically" isn?t amnesty.
Giuliani claimed that "economists" say health insurance rates would fall by up to 50 percent if millions more shopped for policies individually. Once again, his campaign was unable to produce a single economist who supports that figure.
Romney claimed his Massachusetts state insurance program had reduced the number of uninsured in Massachusetts by 300,000. That?s the number who have gained coverage under the system, but many were covered previously through other means.
