Are the parties disenfranchising voters?

I have thought a lot about the punishment given to Michigan and Florida for violating the DNC rules. I think it was rather harsh considering two very important concepts:

1) Elected officials should be representing the will of the people not the will of the parties.

2) Economic losses associated with campaign funds in both states seem punishment enough.

Now that the dates for those primaries are over, why wouldn't the DNC agree to seat the delegates? The same is true for the RNC partial punishment.

I have no doubt that voters in those state feel disenfranchished and rightly so! I think it is wonderful to see the turnouts. It seems as if the voters are saying "we will not be silenced"!

Any thoughts on this? I would love to hear other people's views.
