The feds worry that an electronic voting machine company got purchased by a company in Venezuela; they worry that Hugo Chavez might have some control over the company, and thus control over US elections. However, republicans have said that these machines are so fool-proof that it didn't matter if republican partisans owned such companies.
We really need to get this right. A proper voting system would indeed render meaningless who owns the machine-making company. I have outlined such a system, which would provide redundant and transparent "paper trails", so that various partisan and non-partisan observers would simultaneously know precinct results and certify electronically mastered election outcomes, and each voter would have his/her own evidence of his/her own vote.
