A savvy take from the insider newsletter (subscribers only, alas):

It’s no surprise HRC has gone on the offensive. What is surprising: her angle of attack. When HRC put Obama on his heels re: Pakistan or dictators, it shined the light on her one big advantage – experience. But now, Camp Clinton’s throwing around terms like “slushfund” to undermine Obama’s change message. Problem is, she’s not a particularly effective messenger on “new politics.” Edwards sitting on the sidelines (on purpose?) doesn’t help. Also, Obama has done to HRC on health care what she did to him on Iraq: Blur the differences.
