Here's a little suggestion to you from a Gay Stater (right down I-93 from ya,perhaps).IIRC,NH has the same kind of law that we have down here that allows you to register as "independent" or "unenrolled".By doing so,you can take a ballot for *either* party on primary day and then change to whatever other status you choose (Republican,independent,etc).That was you can,for example,take a democrat ballot and vote for the most outrageous of the candidates (Kusinich?) and really foul up the works.I've done that here in the Gay State and love doing it.Perfectly legal and more fun than you can imagine.
Just a suggestion.
If you remember a lot of us voted for Wallace back in the ‘70’s, very strange feeling. The upside was, at that time you could redeclare on the way out.
