John McCain told the Des Moines Register this week that he always tells "100 percent absolute truth," even in campaign ads. There's one big problem with that bold statement: it's just not true.
McCain has made a number of statements - in paid ads and on the campaign trail - that simply cannot be described as 100 percent accurate. Some aren't even close.
Barack Obama is guilty, too. He falsely accused McCain of wanting to slice Social Security benefits in half and grossly exaggerated his role in writing this year's economic stimulus plan. He also promised to accept public financing - and then proceeded to opt out when it was clear he could raise more money on his own.
But only McCain made this dare: prove it, he told the Register. The paper did not - Politico will.
