I am sure someone has this data.....it would be interesting to see where Ike stood in 56, Nixon in 72, Reagan in 84 ans Clinton in 96 on a month by month basis, just to see if we should be concerned or amused by the 43% number posted by GWB.
I am not much of a Polyanna and am nervous about 43%, yet it is so early, I'd love to know where the reelected ones sat in mid April....May, June, and July, before they each reached their respective conentions.
