politics isn't at fault for the problems in evoting machines - the manufacturers are
Yes and no. The manufacturers could have made them more secure, but the voting machines should also not have ever been in a situation to allow confidential access to the voting data (before or after the election).
It should be common sense by now that nothing is uncrackable, especially something as pervasive and popular and controversial as this. If nobody understood this and individuals were actually allowed to walk off with machines and the data, it really was a political issue - either in the lack of precautions put in place by whoever was in charge, or a lack of appointing someone with the proper experience in the first place.
