Poisoning the Florida well

Alot has been said recently about how Hillary Clinton's tone has changed recently to stop attacking Obama, but isn't this latest Michigan/Florida push damaging as well.

I understand she's trying to keep the balls in the air, but by shouting disenfranchisement in the way that she is, and pointing a finger directly at Obama and the Democratic party, isn't she just inflaming Floridians against her party and the nominee? By her own campaign's assertion, these two states are critical in the fall, so aren't her actions damaging Democratic chances?
