Seems to me that his decison had a racial basis and no a legal basis at all.
Stupid decision on the part of the DOJ.
I think small town elections would be much better without parties. In my small town as in others in TX (and probably the big towns) things get all screwed up at primary election time, because folks want to vote in the major elections for the candidate they like and have to choose a party at that time. Meanwhile they would like to support a local candidate who is running in the other party. Last year was weird because folks were switching to vote democrat to try to change the outcome with that primary election following the advice of talk radio.
The short of it is, every voter should be able to vote for any candidate in local (small town election), even in the primary.
