Well we don't know how everyone is reacting, but at least one has weighed in, California Representative  Dennis Cardoza:

I am deeply concerned about the contentious primary campaign and controversy surrounding the seating of delegates from Florida and Michigan - two states Democrats need to win in November. I will not support changing the rules in the fourth quarter of this contest through some convoluted DNC rules committee process. Yet, we must find a resolution to seat the Michigan and Florida delegates so these states' voters are represented at the Convention. I believe we need to avoid this potentially divisive situation by uniting behind one nominee and bringing the party together immediately. Therefore, I have made the decision to support Senator Obama at the Democratic Convention in my role as a super delegate.

Cardoza was a Clinton superdelegate before today.  There haven't been many signs that the contention over these states is drawing supers to her and here's the first sign that it's annoying people.  Hopefully this will inspire her to ratchet down the rhetoric a level or two.
