I'm in Michigan. Earlier today I received a taped phonecall, urging Democrats to vote in the Republican primary, and vote against Romney.
I wasn't jumping at the idea, but I was considering it. Then we sat down to the evening news. The word from the newscast, as I got it:

To receive a ballot for the Michigan primary, you must first declare your preference, Democrat or Republican. If you do not, you will be given only a ballot for local elections, not including the presidential candidates. If you take a presidential primary ballot, your choice of Repub or Dem will become available public record. That much I'm quite certain I heard correctly, and I don't like it. But it's what I think I heard next that brought me up short. If I heard correctly, my actual candidate vote in the Michigan primary goes on available public record.
1. Can anyone tell me if this is in fact Michigan election law.
2. If so, in how many other states is this true?
3. Does anyone see this as defensible? To me the primary is ultimately part of the presidential election process and should come under the rule of secret balloting.
