GW Bush's rating was very high eight years ago today, he had to come from behind to win in 2004. G HW Bush's rating was very high 20 years ago today, he lost in 1992. This will give him a bump, as one would expect. I don't think it will have much of an impact in November 2012.
Both of the Bush Presidents were Republicans who had to fight the media the entire way. G.W. beat em, barely, Bush Sr. wasn’t able to.
Obama will have the media on his side, running his campaign commercials for him. It isn’t the same.
