The McCain campaign begins to attack Obama for some of his past questionable associations:
"The recent focus on the economy may have contributed to Barack Obama's boost -- but the McCain campaign is fighting back hard, launching a character assault that on Saturday tapped McCain's running mate, Sarah Palin, who accused Obama of "palling around with terrorists" because of his ties to '60s radical William Ayers."
Good. Because it's about judgment.
Look at it this way: suppose John McCain had associated for years with someone who, in 1975, had participated in a bombing of an abortion clinic AND was unrepentant about the act.
Do you think the Obama campaign would agree that such was all ancient history and could be forgotten? I don't think so...
