Louisiana Voter Information
In case you don't want to browse to find this stuff out for yourself, you can obtain a copy of your ballot by going to the ballot selection page on the Louisiana Secretary of State's website and using the location information on your voter registration card to select the appropriate one. You can obtain a non-partisan description of the state constitutional amendments from the Public Affairs Research Council of Louisiana. You can obtain a description of the local propositions from the Secretary of State website by selecting the election and then proposition ids listed on your ballot. Unfortunately, it doesn't show the statutes replaced by some of the propositions, which was quite revealing in my case. Also, the Secretary of State website has a page where you can watch the election returns.
