(1,178 posts)that some reasonable regulation could be put in place to minimize outside "interference." However, from what I am posting in the links, below, it seems that crossover "raiding" is not at all a major issue. I tried to limit to study-based conclusions rather than articles in which people speculate about the subject without disclosing their supporting data. I also included a couple of articles that discuss some of the many registration problems in NY and Massachusetts. Again, sometimes we need to step back and recognize that not everyone is as involved as we are, there are mistakes and irregularities that will happen, and our main goal is to get as many people in this country to vote in each and every election. If that happens, we win.
