Here is a seemingly sympathetic article on ballot access from USA Today. Hat tip to Ricardo Davis of the Georgia CP for drawing my attention to the article.
It is a quirk of American democracy: Your choices for president of the United States depend on which state you live in.
For instance, voters in Colorado and New Mexico who do not want to vote for Mitt Romney or Barack Obama for president will have the option to vote for Virgil Goode of the Constitution Party or for Libertarian Gary Johnson or for several others. But those candidates will not be on the ballot in neighboring Oklahoma.
