Dubya has become a veritable recluse, unlike recent ex-Presidents except for Reagan (and that was a matter of health). The only times that I have seen him in public is at baseball games in Arlington, Texas with Texas Rangers baseball team owner and pitching great Nolan Ryan nearby.
He actually gives alot of speeches and does alot of things, but the media is focused on inside domestic political baseball which Bush is trying to avoid playing.
If Bush pulled a Cheney and said Obama is making America less safe he would be all over the TV for weeks. The speeches like the one he gave today are ignored by the TV media.
