Read part of Plouffe's e-mail, in which he again appeals for more donations, below:

I have some big news we want to share with you.

In the month of June, supporters like you helped raise $52 million. And together with the DNC, we now have nearly $72 million in the bank. That's a very strong financial position to be in.

But we remain at a massive disadvantage to our opponents.

As I mentioned in my video message earlier in the week, the McCain Campaign and the Republican National Committee finished June with nearly $100 million in the bank.

We can't stop now. It's going to take everything we've got to defeat John McCain and his allies in November.
