"Jazzed Up" Democrats in North Carolina

A reader writes:

I went to volunteer for the Obama campaign here in Charlotte, NC at 9:00am.  By the time I got there, they had ran out of stuff for the volunteers to do.  I asked if I could canvass - covered.  I asked if I could take people to their poll precinct - covered.  I ask if I could go to the polling places and help people if there were any problems - covered.   I ask if I could make phone calls - all of the phone lines were taken up so I used my cell phone.  After waiting for an hour, they found a neighborhood that I could canvass.  I canvassed 27 houses.  13 of them had already voted and were eager to tell me that they voted for Obama.  They also thanked me for the work I was doing.  2 weren't so friendly and wouldn't tell me anything and 2 weren't home so I left a friendly reminder on the door.

If this is like anything that is going on across the country, Obama has ground game unlike anything ever seen before and people are jazzed up about it.

(P.S. - Everyone I talked to were white middle class people.)
