ENGLEWOOD, Colorado (CNN) - Alaska Gov. Sarah Palin on Saturday slammed Sen. Barack Obama's political relationship with a former anti-war radical, accusing him of associating "with terrorists who targeted their own country."
Palin's attack delivered on the McCain campaign's announcement that it would step up attacks on the Democratic presidential candidate with just a month left before the November general election.
"We see America as the greatest force for good in this world," Palin said at a fund-raising event in Colorado, adding, "Our opponent though, is someone who sees America it seems as being so imperfect that he's palling around with terrorists who would target their own country."
Palin made similar comments later at a rally in Carson, California.
Obama's Chicago home is in the same neighborhood as Bill Ayers, a founder of the radical Weather Underground that was involved in several bombings in the early 1970s, including the Pentagon and the Capitol, and the two have met several times since Obama's 1995 campaign for an Illinois state senate seat.
