A question of Timing, Kerry/Edwards

1
Today John Kerry announced that John Edwards would be his running mate (not a bad choice) i was wondering how the timing of this announcement plays in concert with the whole election campaign?

(not about the people involved, just want to know more about the timing...)

I have their birth data as Dec 11, 1943 Denver CO 07:10 am for Kerry
and june 10, 1953 Seneca SC 07:02 am for edwards
today is July 6th, 2004. I know the decision was made earlier, but I'm wondering why today for the announcement? etc...

interesting notes about their charts, Suns in opposition at 18 sag and 19 gemini, both have gemini Moons, venus trine venus in sco and tau, both have gemini mars, Edwards has saturn at 20 Lib in full glory... very interesting, and their NN are in opposition at 7 leo and 4 aqu respectively, I find them as a partnership very interesting.
