Where Did The Competent Campaigners Go?

I keep seeing this ridiculous McCain ad being approvingly circulated on conservative blogs, and I am more than a little baffled at how stupid his campaign thinks we are.  The ad claims that Obama is somehow neglecting or ignoring Latin America, as if it were wise for McCain to remind conservatives of his enthusiasm in this area, and it assumes that Latino audiences and the press are both so oblivious that they don’t know that Obama gave a Latin America policy speech in May.  There were problems with the speech he gave, but he has certainly paid some attention to the region.  Understandably, McCain wants to cut into Obama’s lead among Latinos, and he probably thinks he should be able to win over as many as Bush did, but must everything these people do be so unreservedly ill-informed, lame and clueless?
