Obama's then-record-breaking $32M fundraising haul in January was released on February 4. Which just happened to be right before Super Tuesday.
Obama's record-breaking $55M fundraising haul in February was announced on March 6. Two days after the Ohio/Texas campaigns, when he desperately needed to release some good news.
Obama's pretty-darned-good $40M+ fundraising haul in March was announced on April 3, early in the month.
But Obama's now-under-expectations $31M in April wasn't announced until May 20. You remember, the day of the Oregon and Kentucky primary, when everyone was talking about things other than fundraising numbers?
And the May numbers ($22M) weren't announced until June 20. A Friday, aka "bury news day."
So in other words, Obama's campaign gets the importance of the news cycle with respect to fundraising. In the heat of the most competitive primary in recent times, Obama managed to get his fundraising dollars counted in 3-4 days. But now, its taking him 3 weeks to do it?
It is still idle speculation, but we might be in for a treat tomorrow or next Friday (or whatever day they can bury the numbers).
