Yesterday an assasination attempt on Obama was thwarted and Bill Burton went on Fox to call them out for being in the tank for McCain.
Fox might be trying to prove that they're not as conservative as we claim (an effort which will last all of about five minutes, but still), and there may be some actual concern about the results of the hate speech on the right.
His temper is no doubt an issue. Yet if we use his military service to point that out, it'll come back to bite us in the ass.
No Soldier has a perfect record (I sure as hell didn't), and it makes us look bad if we go after his. Pointing out his and Palin's associations with terrorist groups and other extremists is a much more effective way of challenging his character. After all, how can the right bring up Ayers when one of McCain's biggest fundraisers was a sponsor of South American terrorists, and Palin belonged to a anti-American separatist group and went to a church that blamed Jewish unbelief on terror attacks in Israel?
If we want to get into McCain's personal life, we should be talking about his association with racist groups, South American terrorists, and the Keating Five. Talking about a few plane crashes won't be something the American people will care about and will only cause a backlash against us.
