Nonsense. Producing fake paper votes requires a significant investment of effort, and a chance of getting caught, for each fraudulent vote. Fixing an electronic count requires less effort and risk to generate as many fake votes as desired.
Try going to the inner city in a heavily democrat area. Many times the GOP can't even find a monitor to keep things on the up and up, but then they do they are subtly threatened. Then when it comes to actually deliver the votes, its packed into a van that is driven around the highway for hours and hours while special "vote technicians" press out fake votes. There was a great article in the WSJ (relating to the vast vote fraud in Philly) not too long ago in which someone admitted to taking part in this.
