I certainly hope you don't have anything against the President going after his base. This is the same reason you won't see Democrats win in the south or visit military installations, soldiers, Wall Street, etc. The left doesn't have a base in the south or with the military or with businessmen.
The anti-American left have said for the record they think America should plan for the day we aren't strong militarily. Madeline Albright being the most famous to repeat those words. And Wesley Clark. And John Kerry.
John Kerry's votes in the Senate have certainly been to undermine the military, the intelligence community and our weapons systems - at least in this area he's consistent. He doesn't want a strong America and is on record as saying we should NEVER go to war unless we have permission from the UN.
Probably not, or not anything identified for special attention. That's preaching to the choir. He goes to a wide variety of venues. He is especially after swing voters. The group described by Fox News is already heavily Republican.
