MoveOn.org announced they would be sending members out driving a 'One percenter' Cadillac Escalade fully equipped with 'clever' stickers, and even a fake dog strapped to the roof of the car to follow Mitt Romney around as he campaigns. 

MoveOn says they are "in disguise as 1%’ers and derisively mocking him, of course!" 

On what they do:

"Team Romneymobile is following Mitt Romney's "Every Millionaire Counts" bus tour, and is being met at each stop by MoveOn.org members who would be affected by Romney's economic policies that would rig the system further in favor of the 1%. And don't forget to look up, for airline banners that expose Romney as a candidate for President of the 1%, not President of the United States."
