It was posted today, July 16, here. I put a comment on the Christopher Truscott blog, so there's no need to expand on things here.
Follow the link, have a look, and add as a comment there any info you can, if you know of the legal nuances or of IP party rules and/or DFL rules about dual party filing [separate from endorsement] or the primary election consequences of the IP party having endorsed Elwyn Tinklenberg, while apparently having only one filing candidate before the filing deadline had passed. Finally, Anderson may be pressured and cave in to pressure to drop his candidacy in the three day "second thoughts" withdrawal period following expiration of the filing deadline. If that happens it would be news. Presumably Christopher Truscott would be on top of that issue. I defer.
