One of my favorite political-junkie web tools is the Truth-o-Meter at Politi-Fact.com, which is run by The St. Petersburg Times and Congressional Quarterly. Editors rank statements made by and about U.S. presidential candidates on a scale from “True” to “Pants on Fire.”Best bets for entertaining reading (in the “false” and “on fire” categories):

• Rudy Giuliani: “I’m probably one of the four or five best-known Americans in the world.”
• Mike Huckabee: The signers of the U.S. Declaration of Independence were “brave people, most of whom, by the way, were clergymen.”
• Barack Obama: “If we went back to the obesity rates that existed in 1980, that would save the Medicare system a trillion dollars.”
• Hillary Clinton: “It’s just outrageous that under President Bush, the National Institutes of Health have been basically decreased in funding.”
• Joe Biden: “There are 300,000 babies born deformed every year in this country because of women who are alcoholics while they’re carrying those children to term.”
• Mike Gravel (yeah, I know he’s more like a punchline than a candidate): “In 1972, we had a 179,000 human beings in jail in this country. Today, it’s 2.3-million, and 70 percent of them are black, African-American.”
