On April 8, the Pew Center released a comprehensive, objective study of election administration in each state. Here is a link to the Report. The link says the study is dated February 2014, but actually it was just released.
See this news story about the study. The study did not include ballot access, but some of the states found to have the poorest performance happen to be states with severe ballot access laws, such as Alabama, California, and Oklahoma.
