Mathew...there is a pervasive tone of racism and religious bigotry in and around the McCain campaign that is tolerated as long as McCain can say, after the fact, that he doesnt support it.
This incident is only the latest example....not the actions of the woman in question, but the fact that it was McCain's communications director in PA who reported to the media that it was
"a politically motivated attack by a 6'4" black Obama supporter" without knowing the facts.
Other examples,
a mailer from a McCain state campaign staff or republican party official in one state that included an "Obama" dollar with his picture along with fried chicken, watermelon and food stamps.
campaign robo-calls and mailers in other states that question Obama's religion and say that muslims are evil
the list is endless.
But you only see what you want to see.
