There were many issues and flaws that happened using electronic voting machines in the 2006 general election that caused many people to have to re count and re set the new machines to basically re-boot and fix the problem. It was promised that they would make life easier but the system was not prepared and ready for the election which caused many delays and problems.
The general election of 2006 seemed to have had too many high numbers to feel plausible. It was known as one of the highest ones yet, and that makes it seem odd. I do not believe the machines during this time were working as intended or properly. It is uncertain to say for sure though.
