Obama camp very concerned about PA and VA

Via elec, Marc Ambinder forwards the following email from Obama Centcom to Obama New York:

Friends -- Barack needs your help now -- our data indicates that the results will be very close in many states. I can't emphasize enough how urgent this message is. Please go to http://my.barackobama.com/call and start calling as soon as you can. We are not going to hit our goal of 500,000 calls for today by 3pm Central, unless we get at least 2,000 more people calling for the next hour. Can you call now and continue for as long as you can manage? http://my.barackobama.com/call Thank you.
