The Republican campaign, falling behind Obama in polls, plans to make attacks on Obama's character a centerpiece of candidate John McCain's message in the final weeks of the presidential race.
Palin told a group of donors at a private airport, "Our opponent ... is someone who sees America, it seems, as being so imperfect, imperfect enough, that he's palling around with terrorists who would target their own country." She also said, "This is not a man who sees America as you see America and as I see America."
The Obama campaign called Palin's remarks offensive but not surprising in light of news stories detailing the campaign's come-from-behind offensive.
"What's clear is that John McCain and Sarah Palin would rather spend their time tearing down Barack Obama than laying out a plan to build up our economy," Obama campaign spokesman Hari Sevugan said in a statement.
Palin's remark about Obama "palling around with terrorists" comes as e-mails circulate on the Internet with suggestions that the Democratic candidate is secretly a radical, foreign-born Muslim with designs against the U.S. - even though Obama is a native of Hawaii, a Christian and has no connections to Muslim extremists.
Palin, Alaska's governor, said that donors on a greeting line had encouraged her and McCain to get tougher on Obama. She said an aide then advised her, "Sarah, the gloves are off, the heels are on, go get to them."
The escalated effort to attack Obama's character dovetails with TV ads by outside groups questioning Obama's ties to Ayers, convicted former Obama fundraiser Antoin "Tony" Rezko and Obama's former pastor, the Rev. Jeremiah Wright.
Ayers is a professor at the University of Illinois at Chicago. He and Obama live in Chicago's Hyde Park neighborhood and served together on the board of the Woods Fund, a Chicago-based charity that develops community groups to help the poor. Obama left the board in December 2002.
Obama was the first chairman of the Chicago Annenberg Challenge, a school-reform group of which Ayers was a founder. Ayers also held a meet-the-candidate event at his home for Obama when Obama first ran for office in the mid-1990s.
In an interview with CBS News earlier in the week, Palin didn't name any newspapers or magazines that shaped her view of the world. On Saturday, she cited a New York Times story that detailed Obama's relationship with Ayers.
Summing up its findings, the Times wrote: "A review of records of the schools project and interviews with a dozen people who know both men, suggest that Mr. Obama, 47, has played down his contacts with Mr. Ayers, 63. But the two men do not appear to have been close. Nor has Mr. Obama ever expressed sympathy for the radical views and actions of Mr. Ayers, whom he has called 'somebody who engaged in detestable acts 40 years ago, when I was 8."'
Earlier Saturday, Palin spent 35 minutes at a diner in Greenwood Village where she met with Blue Star Moms, a support group of families whose sons or daughters are serving in the armed forces. Reporters were allowed in the diner for less than five minutes before being ushered out by the campaign.
Palin, whose 19-year-old son, Track, deployed last month as a private with an Army combat team, was overheard at one point commiserating with one of the mothers: "Any time I ask my son how he's doing, he says, 'Mom, I'm in the Army now."'
Taking one question from reporters about competing in battleground states, Palin repeated her wish that the campaign had not pulled out of Michigan, a prominent state in presidential elections where Obama leads by double-digit percentage points in recent polls.
"As I said the other day, I would sure love to get to run to Michigan and make sure that Michigan knows that we haven't given up there," she said. "We care much about Michigan and every other state. I wish there were more hours in the day so that we could travel all over this great country and start speaking to more Americans. So, not worried about it but just desiring more time and, you know, to put more effort into each one of these states."
